A Reuters witness said about 200 Palestinians were throwing stones at Israeli military vehicles when a gunshot was heard, adding that a wounded person was then carried to a car.

Israel's military said its forces had been searching in Burqin for suspects involved in the fatal drive-by shooting of an Israeli rabbi from a nearby settlement on January 9.

A military spokeswoman said rioting had broken out while troops were apprehending several suspects connected with that shooting and troops responded with non-fatal "riot dispersal means" against Palestinians throwing rocks and firebombs and then with live gunfire at the main instigators.

The Palestinian Health Ministry said the teenager killed on Saturday was 19, while the hospital in Jenin where he was taken said he had been shot in the head.

The Israeli military spokeswoman said he had climbed onto a military vehicle and opened its door before he was shot.

Israeli forces in the adjacent city of Jenin last month shot and killed a Palestinian gunman whom they had also suspected of involvement in the rabbi's shooting.

Tensions in the region have risen since US President Donald Trump recognised Jerusalem as Israel's capital in December. Since then at least 20 Palestinians and one Israeli have been killed.

Trump's reversal of decades of US policy enraged Palestinians, who want to create an independent state in East Jerusalem, the West Bank and the Gaza Strip.
