In a joint operation, IDF special forces and the Shin Bet (Israel Security Agency) detained Majdi Tzubhi Kasam Mabruk, 31, in the Ein Beit Ilma Refugee Camp in Nablus, where he was believed to command the Abu Ali Mustafa Brigade, the PFLP's military arm.

Security forces said that Mabruk had been involved in a number of attacks against Israeli forces in recent years, including planning suicide operations to be launched from Nablus, as well as planning and carrying out shooting attacks against IDF soldiers operating in the refugee camp. The IDF noted that some of the attacks coordinated by Mabruk had caused casualties to IDF troops.
