RAMALLAH — A Palestinian shot by Israeli soldiers in the occupied West Bank died of his wounds on Tuesday, a hospital official said, the third Palestinian killed in a flare-up of violence over the past week.

The Israeli military said soldiers spotted several Palestinians trying to cut through Israel’s barrier in the West Bank, near the Jewish settlement of Shaked, on Monday and called on them to halt.

“When they refused, the forces responded with fire toward an instigator’s lower extremities,” a military spokeswoman said.

Mohammad Saleh, 18, was hit in a main artery and doctors were unable to save him, said Tarif Ashour, a Palestinian Health Ministry official.

Violence has flared intermittently since Israelis killed a Palestinian youth in Jerusalem in an alleged revenge for the Palestinian killing of three Israeli teenagers last year, just before last year’s 50-day war with the Hamas militants who control Gaza.

One of Saleh’s relatives said the teenager was walking in fields near the barrier after a wedding celebration and had not attempted to cross it.

On Saturday, Israeli security forces killed two knife-wielding Palestinian attackers in separate incidents in the West Bank city of Hebron and in East Jerusalem, Israeli police said.

The family of one of the alleged assailants, 17-year-old Ali Abu Ghannam, said he was unarmed and on his way home from a party in East Jerusalem.

Also on Saturday, three Israeli police officers were injured when a car rammed into them in a Palestinian neighborhood in East Jerusalem. Police said it was a deliberate attack and that they arrested the driver, who fled the scene, hours later.
