New violence rocked Israel and the West Bank on Wednesday, including a stabbing in annexed east Jerusalem, even as Israel and Palestinian President Mahmud Abbas took steps to ease tensions.

The knife attack in Jerusalem's Old City, in which a Palestinian woman stabbed a Jewish man before being shot and seriously wounded, was the second in the walled heart of the city in days.

Russian military officials were to hold talks with their Israeli counterparts in Tel Aviv on Tuesday after the countries' leaders agreed to establish a mechanism to avoid accidental clashes in Syria.

Israel's military confirmed the two-day meeting on "regional coordination," which comes after Prime Minister Benjamin Netanyahu and Russian President Vladimir Putin held talks last month related to Syria.

Germany voiced concern Monday about the risk of a "new intifada" following clashes in Jerusalem, three days ahead of a Berlin visit by Israeli Prime Minister Benjamin Netanyahu.

"What possibly awaits us here is something like a new intifada," said foreign ministry spokesman Martin Schaefer.

New clashes erupted Monday in the West Bank and east Jerusalem while Israel's military shot dead a 13-year-old Palestinian after Prime Minister Benjamin Netanyahu pledged a crackdown following attacks that killed four Israelis.

The spike in violence has led to international calls for calm, with concerns the unrest could spin out of control and memories of previous Palestinian uprisings still fresh.

Ten Palestinians were wounded by Israeli fire in the West Bank on Saturday during a raid by troops hunting the murderers of a Jewish settler couple, Palestinian police and medical sources said.

Palestinians protesting against the raid in the territory's main northern city of Nablus hurled stones at soldiers, who responded with rubber bullets, tear gas and live ammunition, the sources said.

Hundreds of Israeli troops were hunting Friday for suspected Palestinian gunmen after the killing of a settler couple as they drove through the occupied West Bank with their young children.

Eitam and Naama Henkin, both in their 30s, were shot dead in their car on Thursday night as they traveled between the settlements of Itamar and Elon More, in the north of the Palestinian territory.

Israel is considering authorizing wildcat settlement outposts in the West Bank near a village where a firebombing killed an 18-month-old Palestinian boy and his parents, court documents showed Thursday.

The government confirmed it was considering the authorization in a court document first made public by rights group Yesh Din, which has been involved in legal action against one of the outposts.

Mahmud Abbas's U.N. declaration that he is no longer bound by accords with Israel has the potential to upturn what remains of the peace process, but there are doubts whether concrete actions will follow.

His speech on Wednesday at the United Nations General Assembly was seen as both an attempt to draw renewed focus to the Palestinian cause as well as a bid for leverage at a time when the world's attention is focused elsewhere.

A group of Israeli Arabs accused of forming an Islamic State group-inspired cell with plans to attack security forces and stores selling alcohol were charged in an Israeli court Thursday, police said.

The group included three members aged 20-23 from the northern Israeli city of Nazareth and adjacent town Yafia, as well as another 26-year-old who allegedly provided them with guidance from prison, where he is already serving time for murdering a taxi driver.

Israeli air raids have hit the Gaza Strip in response to a rocket fired from the Palestinian enclave that was intercepted by the Iron Dome missile defense system, officials said Wednesday.

There were no reports of injuries from both the rocket fire and the Israeli raids, which the military said targeted "four terror sites".
