Martyr Muhammad al-Deif Brigades (Arabic : كتائب الشهيد محمد الضيف, romanized: kataib al-shahid muhammad al-daif) is a militant organization in Syria. [1]
Its name is due to Mohammed Deif, the former military commander of Hamas's Izz al-Din al-Qassam Brigades, who was killed in an Israeli airstrike in July 2024 during the Gaza war. [2] [3]
It was founded on 31 May 2025, and issued a "founding declaration" in central Palestine [4] where they declared: "Based on the saying of the Almighty: 'And prepare against them all your power, including warhorses with which you may terrify the enemy of Allah and your enemy,'" they paid tribute to deceased Hamas leaders. [5]
On 3 June, a barrage of Grad rockets was fired at Israel from Tasil, setting off sirens in northern Israel and the Golan Heights. The rockets struck open areas near Ramat Magshimim, and the IDF responded with artillery fire. [6] A second barrage was fired minutes later, but it is unclear if it came from Syria. [7] Martyr Mohammed Al-Deif Brigade claimed responsibility for the attack. [8] [9]
Hamas denied any relationship with the Martyr Muhammed al-Deif Brigades, disavowing its composition and leadership. [8] [10]
On June 8, they launched attacks on the Israeli army from the Gaza Strip [11] [12]
