Chairman of the Palestine Liberation Organization Mahmoud Abbas said Friday night that Palestinian militants' attacks against Israel can not be justified.

Abbas made the remarks in the West Bank town of al Beera in response to an ambush carried out by al Aqsa martyrs brigades, the armed wing of Fatah, against an Israeli vehicle near the West Bank town of Nablus.

One Israeli was killed and three others were injured in the attack.

"Attacks have its reasons and motives, but I don't justify anybody to carry out these attacks. But in the same time, there aremany reasons, there is an occupation and there are many issues I don't want to go into it now," he said.

He revealed that Al Aqsa Martyrs Brigades promised him that theywould be committed to his program once he was elected as the new Palestinian leader in Sunday's elections, adding that he hoped a new era would begin.

The group said in a leaflet distributed in the northern part of the West Bank that the attack is to revenge the Israeli army military actions carried out against the Palestinians.
