People in the Gaza Strip on Monday made their way through debris left in the aftermath of Israeli bombardment in what the army said were suspected guerrilla sites in the coastal territory, in what is the sixth day of fighting between Israel and Hamas.

Some buildings were blazing with fire in the early hours of the morning as residents used shovels to try and stifle them.

At one local hospital the bodies of those killed filled the morgue, and at least two wounded young boys being treated.

The latest strike has brought the number of Palestinians killed in Gaza strikes to 83.

Eight people, including three children and three gunmen, were killed and at least 30 other Palestinians were injured in the latest air strikes.

United Nations Secretary General Ban Ki-moon was due to arrive in Cairo to weigh in on ceasefire efforts led by Egypt, which borders both Israel and Gaza and whose Islamist-rooted government has been hosting leaders of Hamas.

Israeli media said a delegation from Israel had also been to Cairo for truce talks, though a spokesman for Prime Minister Benjamin Netanyahu’s government declined to comment on the matter.

The Gaza flare-up, and Israel’s signalling that it could soon escalate from the aerial bombings to a ground sweep of the cramped and impoverished enclave, have stoked the worries of world powers watching an already combustible region.

As a precaution against the rocket interceptions endangering nearby Ben-Gurion International Airport, civil aviation authorities said on Monday new flight paths were being used. There was no indication takeoffs and landings at Ben-Gurion had been affected.
