Four of the five were children.

JERUSALEM (Reuters) – A Palestinian man threw a chemical substance believed to be acid at an Israeli family in the occupied West Bank on Friday, injuring a man and four children, Israeli police and the military said.

The assailant was shot and wounded immediately after the attack, which took place at a checkpoint south of Jerusalem.

Police spokeswoman Luba Samri said the attacker had “poured an unknown substance suspected to be acid on a Jewish family.” She said a civilian at the scene shot and wounded the assailant.

The incident comes at a time of heightened tension between Palestinians and Israelis, particularly in the West Bank and East Jerusalem, territories Israel seized in a 1967 war and Palestinians want for an independent state, together with Gaza.
