Hussein Qawariq, 59, from the village of Awarta, was shot on Tuesday by Israeli occupation forces manning a checkpoint in Huwara, near the West Bank city of Nablus, the Palestinian health ministry said.

The Israeli army told AFP that soldiers "spotted a suspect approaching them at a military post" and initially fired in the air after "receiving no response".

"The suspect continued approaching the soldiers who responded with fire toward him. A hit was identified," the army said.

Huwara mayor Wajih Odeh told AFP Qawariq was "mentally disabled". He "used to collect bottles and cans from the street and ask for money from businesses in the area", he said.

Qawariq's family too said he had a "mental disorder," Palestinian news agency WAFA reported. He succumbed to his wounds in the Rabin Medical Center in Israel, it added.

The occupation army said it was looking into the fatal shooting.

At least 54 Palestinians have been killed since late March, mostly in the occupied West Bank. They have included suspected militants and also non-combatants, among them Al Jazeera journalist Shireen Abu Akleh, a Palestinian-American dual national, who was covering an Israeli raid in Jenin.

Attacks on Israeli targets have killed 19 people over the same period in attacks inside Israel. Three Israeli Arab attackers have also been killed.
