More than 300 West Bank gunmen have so far surrendered their weapons as part of an amnesty deal with Israel, a senior Palestinian security official said on Sunday. The gunmen included in the deal are members of the Al Aqsa MartyrsÂ’ Brigades, a violent offshoot of moderate President Mahmoud AbbasÂ’ Fatah movement. Al Aqsa was founded at the outbreak of the second Palestinian uprising against Israeli occupation in 2000, and its members carried out scores of shooting attacks. The Palestinian official spoke on condition of anonymity because he is not permitted to discuss the issue with reporters.
