On 2 April 2005, President Abbas dismissed West Bank national security chief General Haj Ismail Jaber. The reason given was a shooting incident on 30 March inside Abbas’ headquarters in which militants fired into the air. Abbas also fired Ramallah security chief Yunis al-Has. Abbas placed the security services in Ramallah on a “state of alert”. A large-scale reform of the security services followed that month. On 22 April, head of the Gaza Security Forces Moussa Arafat was replaced by Suleiman Heles.
