A Palestinian gunman killed two Jewish settlers in the car they were traveling in on Sunday in the occupied West Bank, sparking attacks by Israeli settlers on homes and cars that killed one Palestinian, officials said.

There has been no claim of responsibility for the incident, which coincided with talks between Israeli and Palestinian security officials in Aqaba, Jordan, in which both sides pledged to “prevent further violence” and work towards “de-escalation”.

The Israeli military said the gunman reached an intersection “and opened fire on an Israeli vehicle.”

It said the victims near Hawara, an area with regular clashes between Palestinians and settlers, were brothers from Har Bracha, a settlement 8km away. One was a soldier in a program for Jewish seminary students.

Following the incident, Palestinians reported that Israelis from a nearby settlement attacked Palestinian homes in the area.

Ghassan Douglas, an official in charge of anti-settlement activities, said several Palestinian homes and 15 cars were set on fire.

A 37-year-old Palestinian man was shot dead by an Israeli settler, Palestinian officials said. The Israeli military, which was operating in the area, had no immediate comment.

Palestinian President Mahmoud Abbas held the Israeli government fully responsible for the attacks.

Israeli Prime Minister Benjamin Netanyahu said soldiers were hunting the attacker who killed the two Jewish settlers, and the military said it had cordoned off the area.

“I ask that even when blood boils, no one takes the law into their own hands. I ask that the IDF and security forces be allowed to do their job,” Netanyahu said.

The European Union’s Middle East envoy Sven Koopmans said he was “dismayed by the spiral of violence” and called on all authorities “to act to immediately end the bloodshed and impunity and prevent further casualties.”

Following the first meeting of its kind between Palestinians and Israelis in years, with regional and international participation on the situation in the Palestinian Territories, the Israeli government and the Palestinian National Authority “reaffirmed their shared will and commitment” to act immediately to stop the unilateral measures for a period of 3 to 6 months. This includes Israel’s commitment to halt discussions on the creation of new settlement units for a period of 4 months and not to legalize “illegal” settlements for a period of 6 months, according to the communique.

However, Israel’s far-right finance minister said shortly afterwards that he would not agree to any freeze on settlement activities in the occupied West Bank, and for its part, the Palestinian militant group Hamas stressed that the meeting in Aqaba was “worthless” and that it would not change nothing.
