Ramallah, June 09: Palestinian leader Yasser Arafat has appointed a new head of preventive security in the West Bank, a senior Palestinian security source said today. Ziad Habrih from the northern West Bank city of Jenin will replace Zuhair Manasra, the source told a news agency on condition of anonymity. Habrih is close to former chief Jibril Rajoub whom Arafat sacked last year, and his appointment was made in consultation with the security chief in Prime Minister Mahmud Abbas' government, Mohammed Dahlan, the source added. The preventive security services will make up the bulk of the apparatus the Palestinian authority is trying to rebuild in a bid to re-establish its grip on security and crack down on radical anti-Israeli militants.
