On 4 December 2022 a mass die-off of Caspian seals (Pusa caspica) in the Caspian Sea was reported. Initially over 140 Caspian seals were found dead on the beaches of Kazakhstan. [1] By 5 December around 2,500 dead Caspian seals have been found on Dagestan's shore. No conclusive cause of the die-off has been established. Dagestan's Ministry of Natural Resources believed the animals had died of "natural factors" and estimated the number of dead seals was likely to be much higher. [1] While Caspian seal is an endangered species, Dagestan's Ministry of Natural Resources said their overall number in the area remained stable, "ranging from 270,000 to 300,000" (while the Caspian Environmental Protection Center put the number at 70,000). [2]
Initially it was reported that 700 dead seals had been found on the shore, but the Ministry of Natural Resources and Environment of Russia later revised the number to about 2,500. [2]
Dagestan's Ministry of Natural Resources said there were "no signs of violent death, no remains of fishing nets" and that judging by their appearance, the seals died about two weeks before their discovery (in November). [1] Specialists from the Caspian Environmental Protection Center started to analyze samples from the dead seals to find the cause of death. [1] No signs of pollutants were immediately found. [2]
According to Russian journalist Yulia Latynina, the seals died because of toxic fuel of air-launched cruise missile from Russian bombers Tu-95 and Tu-160 deployed over Caspian Sea in the 2022 Russian invasion of Ukraine. According to this version, some missiles malfunction due to their old age and fail to launch. [3] To avoid their accidental falls on land, launches are made over water. [3] Since the start of the invasion several mass die-offs of Caspian seals were recorded (such as in spring when between 31 March and 2 May 832 carcasses were found in Kazakhstan's Mangystau Region and in summer when 837 carcasses were found on Kazakhstan's coast).

Kazakhstan is located in Central Asia. With an area of about 2,724,900 square kilometers (1,052,100 sq mi) Kazakhstan is more than twice the combined size of the other four Central Asian states and 60% larger than Alaska. The country borders Turkmenistan, Uzbekistan, and Kyrgyzstan to the south; Russia to the north; Russia and the Caspian Sea to the west; and China's Xinjiang Uygur Autonomous Region to the east.
Turkmenistan is a landlocked country in Central Asia, bordering the Caspian Sea to the west, Iran and Afghanistan to the south, Uzbekistan to the north-east, and Kazakhstan to the north-west. It is the southernmost republic of the Commonwealth of Independent States (CIS), the loose federation created at the end of 1991 by most of the Post-Soviet states.
The Tupolev Tu-160 is a supersonic, variable-sweep wing heavy strategic bomber designed by the Tupolev Design Bureau in the Soviet Union in the 1970s. It is the largest and heaviest Mach 2+ supersonic military aircraft ever built and second to the experimental XB-70 Valkyrie in overall length.

The Russian Gepard-class frigates, Russian designation Project 11661, is a class of frigates that were intended as successors to the earlier Koni-class frigates and Grisha, and Parchim-class corvettes. The first unit of the class, Yastreb (Hawk), was laid down at the Zelenodol'sk Zavod shipyard at Tatarstan in 1991. She was launched in July 1993, after which she began fitting out; fitting was nearly completed by late 1995, when it was suspended due to lack of funds. Renamed Tatarstan, the ship was finally completed in July 2002, and became the flagship of the Caspian Flotilla. She has two sister ships, Albatross, and Burevestnik, which was still under construction as of 2012.
Tengiz field is an oil field located in northwestern Kazakhstan's low-lying wetlands along the northeast shores of the Caspian Sea. It covers a 2,500 km2 (970 sq mi) project license area which also includes a smaller Korolev field as well as several exploratory prospects.
The Kh-55 is a Soviet/Russian subsonic air-launched cruise missile, designed by MKB Raduga in the 1970s. It has a range of up to 2,500 km (1,350 nmi) and can carry nuclear warheads. Kh-55 is launched exclusively from bomber aircraft and has spawned a number of conventionally armed variants mainly for tactical use, such as the Kh-65SE and Kh-SD, but only the Kh-101 and Kh-555 appear to have been put into service. Contrary to popular belief, the Kh-55 was not the basis of the submarine and ground-launched S-10 Granat or RK-55 Relief designed by NPO Novator. The RK-55 is very similar to the air-launched Kh-55 but the Kh-55 has a drop-down turbofan engine and was designed by MKB Raduga.
The Kh-22 is a large, long-range anti-ship missile developed by MKB Raduga in the Soviet Union. It was designed for use against aircraft carriers and carrier battle groups, with either a conventional or nuclear warhead. Kh-32 is the upgraded conventional/nuclear variant of Kh-22 and was accepted to service in 2016, it features an improved rocket motor and a new seeker head.
The Caspian seal is one of the smallest members of the earless seal family and unique in that it is found exclusively in the brackish Caspian Sea. They are found not only along the shorelines, but also on the many rocky islands and floating blocks of ice that dot the Caspian Sea. In winter, and cooler parts of the spring and autumn season, these marine mammals populate the Northern Caspian. As the ice melts in the summer and warmer parts of the spring and autumn season, they can be found on the mouths of the Volga and Ural Rivers, as well as the southern latitudes of the Caspian where cooler waters can be found due to greater depth.
The Caspian Flotilla is the flotilla of the Russian Navy in the Caspian Sea.
The Zvezda Kh-35 is a Soviet turbojet subsonic cruise anti-ship missile. The missile can be launched from helicopters, surface ships and coastal defence batteries with the help of a rocket booster, in which case it is known as Uran or Bal. It is designed to attack vessels up to 5,000 tonnes.
The Dagestan War, also known as the Invasion of Militants in Dagestan began when the Chechnya-based Islamic International Peacekeeping Brigade (IIPB), an Islamist group, led by Shamil Basayev, Ibn al-Khattab, Ramzan Akhmadov and Arbi Barayev, invaded the neighboring Russian republic of Dagestan, on 7 August 1999, in support of the Shura of Dagestan separatist rebels. The war ended with a major victory for the Russian Federation and Dagestan Republic, and the retreat of the IIPB. The invasion of Dagestan served as the main casus belli alongside the series of apartment bombings in September 1999 for the Second Chechen War.
The 3M-54 Kalibr,, also referred to it as 3M54-1 Kalibr, 3M14 Biryuza, is a family of Russian cruise missiles developed by the Novator Design Bureau (OKB-8). There are ship-launched, submarine-launched and air-launched versions of the missile, and variants for anti-ship, anti-submarine and land attack use. Some versions have a second propulsion stage that initiates a supersonic sprint in the terminal approach to the target, reducing the time that target's defense systems have to react, while subsonic versions have greater range than the supersonic variants. The missile can carry a warhead weighing up to 500 kilograms (1,100 lb) of explosive or a thermonuclear warhead.
The mineral industry of Kazakhstan is one of the most competitive and fastest growing sectors of the country. Kazakhstan ranks second to Russia among the countries of the CIS in its quantity of mineral production. It is endowed with large reserves of a wide range of metallic ores, industrial minerals, and fuels, and its metallurgical sector is a major producer of a large number of metals from domestic and imported raw materials. In 2005, its metal mining sector produced bauxite, chromite, copper, iron, lead, manganese, and zinc ores, and its metallurgical sector produced such metals as beryllium, bismuth, cadmium, copper, ferroalloys, lead, magnesium, rhenium, steel, titanium, and zinc. The country produced significant amounts of other nonferrous and industrial mineral products, such as alumina, arsenic, barite, gold, molybdenum, phosphate rock, and tungsten. The country was a large producer of mineral fuels, including coal, natural gas, oil, and uranium. The country's economy is heavily dependent on the production of minerals. Output from Kazakhstan's mineral and natural resources sector for 2004 accounted for 74.1% of the value of industrial production, of which 43.1% came from the oil and gas condensate extraction. In 2004, the mineral extraction sector accounted for 32% of the GDP, employed 191,000 employees, and accounted for 33.1% of capital investment and 64.5% of direct foreign investment, of which 63.5% was in the oil sector. Kazakhstan's mining industry is estimated at US$29.5 billion by 2017.
The Caspian Sea is the world's largest inland body of water, often described as the world's largest lake or a full-fledged sea. An endorheic basin, it lies between Europe and Asia; east of the Caucasus, west of the broad steppe of Central Asia, south of the fertile plains of Southern Russia in Eastern Europe, and north of the mountainous Iranian Plateau of Western Asia. It covers a surface area of 143,550 sq mi (372,000 km2) and a volume of 78,200 km3 (19,000 cu mi). It has a salinity of approximately 1.2%, about a third of the salinity of average seawater. It is bounded by Kazakhstan to the northeast, Russia to the northwest, Azerbaijan to the southwest, Iran to the south, and Turkmenistan to the southeast.
Dagestan Airlines Flight 372 was a scheduled commercial flight between Moscow's Vnukovo Airport and Makhachkala, Russia.

Bogdinsko-Baskunchakski Nature Reserve is a Russian 'zapovednik' in a semi-arid area around two notable features: Lake Baskunchak, Russia's largest undrained salt lake, and Big Bogdo Mountain, the highest point in the Caspian Depression and home to the "singing rocks". It is about halfway between Volgograd and Astrakhan, placing it about 200 km north of the Volga River Delta, where the river enters the Caspian Sea from the northwest. About 20 km east of the lake is the border with Kazakhstan. Baskunchak has been a source of salt to Russia for centuries. The reserve is an important site on the bird migration route between northern Siberia and wintering regions. The reserve is situated in the Akhtubinsky District of Astrakhan Oblast.
Dagestan Nature Reserve is a Russian 'zapovednik' that protects an area of sand dunes and ridges on the northwest coast of the Caspian Sea in the southeast of European Russia. The reserve, a wintering place for migratory birds, is the richest nature reserve in Russia in terms of the number of species - over 300 species have been recorded in the reserve, its buffer zones and subordinate reserves. The reserve is part of several "Important Bird and Biodiversity Areas" (IBAs). The Sarykum sand dune is the highest sand dune in Europe, at 262 m (860 ft). The reserve is situated in the Tarumovsky District of Dagestan.

The 2022 Russian strikes against Ukrainian infrastructure are drone and missile strikes against Ukraine's infrastructure, conducted by Russia as part of the 2022 Russian invasion of Ukraine. In violation of the rule of war, most targets were civilian areas beyond the battlefield and critical energy infrastructure in particular, which is considered a war crime. The campaign has been credited to Russian general Sergey Surovikin, who took overall command of Russia's war in Ukraine two days before the campaign's start, and had implemented similar tactics in Syria.
