Israeli forces are searching for an assailant behind an attack that killed a soldier at an east Jerusalem checkpoint, authorities said, hours after two Palestinian teenagers were shot dead in an Israeli raid in the occupied West Bank.
The Israeli army said a soldier had been "killed as a result of being critically injured by a shooting attack".
Police said the incident took place in Israeli-annexed east Jerusalem near Shuafat Palestinian refugee camp.
Another Israeli had been "severely injured", police said, and a third person, whose nationality was not specified, was hit by "shrapnel" in the incident, according to emergency services group Magen David Adom (MADA).
MADA added that all gunshot victims were aged in their 20s.
Police cordoned off the area near the checkpoint and dozens of officers had been deployed at the entrance and exit of east Jerusalem, while the Palestinian Red Crescent Society said its medics were being prevented from entering the refugee camp.
Israeli Prime Minister Yair Lapid described the shooting as a "severe" attack.
"My heart is with the wounded and their families this evening. Terror will not defeat us, we are strong even on this difficult evening," he said in a statement.
Earlier, two Palestinian teenagers were shot dead in an operation by Israeli forces in Jenin, the flashpoint northern city in the occupied West Bank.
The Palestinian health ministry announced the killing of "two citizens by occupation (Israeli) bullets in Jenin", as Israeli troops carried out an arrest there.
Eleven others were also wounded.
Israel's military said troops entered Jenin yesterday to detain a 25-year-old Palestinian it said was a member of the Islamic Jihad militant group and suspected of shooting at troops in the area.
"During the activity, dozens of Palestinians hurled explosive devices and Molotov cocktails at IDF soldiers and shots were fired at them," an army statement said, adding that soldiers fired at "the armed suspects".
Following the latest deaths in Jenin, the Palestinian presidency called on Washington to "exert serious pressure on Israel to stop its all-out war against our Palestinian people".
Israeli action "will push matters towards an explosion and a point of no return, which will have devastating consequences for all," said Nabil Abu Rudeineh, spokesman for president Mahmud Abbas, in a statement published by the official Palestinian news agency Wafa.
The agency also reported Israeli forces fired directly at journalists during the Jenin raid.
