The head of the military wing of the Palestinian Islamist group Hamas has been killed during a series of Israeli air strikes in the Gaza Strip.

Ahmed Said Khalil al-Jabari and another Hamas official died when the car they were travelling in was hit in Gaza City.

It was part of a wider Israeli operation against militant groups in the Hamas-run Gaza Strip.

It follows a wave of rocket attacks against Israel from the territory.

Outside the hospital where Mr Jabari's body was taken, thousands of angry Gaza residents chanted "retaliation" and "We want you to hit Tel Aviv tonight", according to the Associated Press news agency.

Gaza's interior ministry said a further four Palestinians had died in the attacks across Gaza.

Militants in Gaza have fired more than 110 rockets towards southern Israel since Saturday, when four soldiers were wounded in an anti-tank missile attack on an Israeli army jeep.
