The US says a Palestinian-American youth was killed by Israeli troops during clashes on Friday and demanded a swift and transparent investigation.
Orwah Hammad, 14, was shot in the head in the Palestinian village of Silwad, near Ramallah.
An Israeli army spokesman told Reuters Israeli forces "managed to prevent an attack when they encountered a Palestinian man hurling a molotov cocktail at them on the main road next to Silwad. They opened fire and they confirmed a hit."
US State Department spokesperson Jen Psaki called for a "speedy and transparent investigation."
"The United States expresses its deepest condolences to the family of a U.S. citizen minor who was killed by the Israeli Defense Forces during clashes in Silwad on October 24," she said, adding that US officials would remain "closely engaged with the local authorities, who have the lead on this investigation."
