BETHLEHEM (Ma'an) -- A man shot by Israeli forces in north Gaza died late Monday, Palestinian medics said.

Mustafa Abu Jarad, believed to be a farmer, was shot in the head in the town of Beit Lahiya on the border with Israel, Gaza's health ministry said earlier Monday.

The 21-year-old was taken to Shifa hospital but died later, said doctors.

An Israeli military spokeswoman said officials had checked "and apparently the incident is not related to the Israeli army".

A source speaking on condition of anonymity said Israel suspected the man was shot by a fellow Palestinian.

Three Palestinians have been shot dead by Israeli soldiers along the border since the end of an eight-day offensive in November. Some 30 people have been wounded in the incidents, Gaza officials say.

Palestinians say the restrictions stop many farmers getting to their fields.
