The Palestinian Liberation Organization called Saturday for a comprehensive strategy against Islamic extremism while addressing the conflict with Israel, alluding to controversial remarks by U.S. Secretary of State John Kerry.

Hizbullah chief Sayyed Hassan Nasrallah has reportedly visited his party's fighters on the Lebanese-Syrian border dressed in military fatigues in a strong show of support.

U.S. Secretary of State John Kerry on Thursday called for a resumption of the Israel-Palestinian peace process, saying the talks were vital in the fight against extremism.

"It is imperative that we find a way to get back to the negotiations," Kerry said at a State Department ceremony marking the Muslim festival of Eid al-Adha.

Israeli Defense Minister Moshe Yaalon said Wednesday that Hizbullah might have more self-confidence, days after the party's chief Sayyed Hassan Nasrallah pledged to defeat jihadists and expressed readiness for a new confrontation with the Jewish state.

Israeli settlers in the occupied West Bank allegedly carried out an arson attack on a mosque near the city of Nablus early on Tuesday, Palestinian security sources told AFP.
