Counter-Terrorism Strike Force

The CTSF was founded on 21 August 2025 during the societal breakdown within Gaza, stating to combat the "repression and terrorism practiced by Hamas". It was founded in the village of Qizan an-Najjar, south of Khan Yunis. == History ==

The group was founded by Hosam al-Astal, a Palestinian Bedouin who worked in Israel and then worked for the Palestinian Authority's National Security Forces (NSF) when they still controlled the Gaza Strip. He has spoken favourably about the era of direct Israeli military rule in Gaza prior to the 2005 disengagement. Al-Astal was previously imprisoned and given a death sentence by Hamas for his involvement with Israel, and was accused of involvement in the 2018 assassination of Fadi Mohammad al-Batsh, an engineer associated with Hamas' al-Qassam Brigades in Malaysia, who had allegedly went there in order to improve the design of the Hamas Qassam rocket. == Organization and structure ==

The CTSF's leadership consists largely of figures affiliated with the Palestinian National Liberation Movement—better known as Fatah—mainly from Hosam al-Astal's extended family. The CTSF controls the village of Qizan an-Najjar, where it is also headquartered. == Relations ==

The neo-conservative Foundation for Defense of Democracies (FDD) said that the CTSF is supported by Israel's Shin Bet and the Israeli Defense Forces (IDF). Its leader, Hosam al-Astal, also has links to the Mossad. Al-Astal has justified his group's relationship with Israel as "the only way to survive" for his group. According to The Jerusalem Post the CTSF and the Popular Forces are reportedly in contact with one another but work independently. Before founding the Counter-Terrorism Strike Force, Ynet reported that al-Astal was a member of the Popular Forces. == Operations ==

Al-Astal has said that the CTSF helped defend the al-Mujaida clan of Khan Yunis after Hamas forces launched a raid on the clan on 3 October 2025. It marked the first time the group battled Hamas. In October 2025, the CTSF reached an agreement with the Israeli Defense Forces (IDF) to establish a "Green Line" where no fighting would take place. In November 2025, al-Astal told Israeli media that "U.S. representatives" had stated that his group would play a part in the future police force in Gaza. Al-Astal, who once worked with the Palestinian Authority (PA), said that he and his group coordinated with Israel to bring supplies to the CTSF and expressed interest to collaborate with PA and the United States. In January 2026, the CTSF claimed responsibility for the assassination of 40-year-old Lieutenant Colonel Mahmoud al-Astal, the head of investigations and the criminal police unit of the Gazan police in Khan Yunis and also a relative of Hosam al-Astal. == Administration ==

The CTSF is headquartered in Qizan an-Najjar and operates primarily in southeastern Khan Younis, with a notable presence in Jorat al-Lout, and al-Manara. == See also ==
