A group of 200 men calling themselves members of the "Jihad Bombers Force" (PBJ) in Pontianak, capital of Indonesia's West Kalimantan province, are ready to leave for Palestine and Lebanon to paralyze Israeli vital facilities if the latter fails to abide by a 4-days deadline.

"We give Israel 4-days deadline as of now to stop its military aggression against Palestine and Lebanon. If this ultimatum is ignored, we will not be responsible for the 200 voluntary jihad bombers who are going to leave for the two Middle Eastern countries," Antara news agency quoted Indonesian Human Rights spokesman Suib Didu as saying in Pontianak on Saturday.

He said the jihad bombers would not only launch attacks in Palestine and Lebanon but also in countries allied with Israel.

"If Israel does not stop its military aggression, we from the State Defense Volunteers (RBN) will not hold back the action of PBJ to retaliate the Israeli attacks," Suib Didu said.

He said around 3,117 volunteers had registered themselves to defend Palestine and Lebanon in their war against Israel.

He said that while in the battle fields, the jihad warriors would not directly face Israeli forces but use a guerrilla strategy by attacking Israel from behind.
