A Palestinian man who wounded an Israeli in a knife attack on Saturday evening was killed by police, just hours after another Palestinian killed two Israeli men, police said.

The latest death occurred when the Palestinian man stabbed a passerby on the street in west Jerusalem before being shot dead by police.

The United States condemned the attack which killed the two people and injured two others in Jerusalem’s Old City.

Washington “strongly condemns all acts of violence, including the tragic stabbing in the Old City of Jerusalem today,” State Department spokesman John Kirby said in a statement.

“We are very concerned about mounting tensions in the West Bank and Jerusalem, including the Haram al Sharif/Temple Mount, and call on all sides to take affirmative steps to restore calm and avoid escalating the situation,” he added.

A Palestinian said to be an Islamist killed two Israeli men and injured a woman and a toddler in a knife and gun attack in Jerusalem Saturday, in a fresh escalation of violence.

The attack in the Old City came with Israeli security forces on alert after recent clashes at the city’s flashpoint Al-Aqsa mosque compound and the murder in the West Bank of a Jewish settler couple in front of their young children.
