A Palestinian gunman killed one person and wounded at least three others in a Jewish settlement in the occupied West Bank before being shot dead by a guard, the Israeli military, medics and a settlement representative said.
The militant group Hamas claimed the Hebron gunman as its member.
Itamar Ben-Gvir, a far-right politician from the settlement whose Religious Zionism party is projected to win third place in Israel's election on Tuesday, was unharmed.
“I say to these terrorists, if they think that threats, that attempted murder will deter me — it won't help you. I am pressing ahead,” Mr Ben-Gvir told Israel's Channel 12 TV.
Violence in the West Bank, among territories where Palestinians seek statehood, has escalated since Israeli forces launched a crackdown in March in response to a string of attacks by Palestinians within Israel.
A settlement representative said four people were wounded in the shooting near a checkpoint in Hebron, where hundreds of settlers live in an uneasy standoff among hundreds of thousands of Palestinians.
One of those casualties, a middle-aged man, was later declared dead. It was not clear if he held Israeli citizenship.
Israel's Magen David Adom ambulance service said a Palestinian had also been slightly wounded in the incident.
The Palestinian Red Crescent ambulance service said one of its crew members in Hebron was hit in the shoulder by Israeli gunfire. The Israeli military made no comment on that.
