Israel Army tells all Gaza City residents to flee heavy battles

Israeli Army drops leaflets urging Gaza City residents to flee heavy offensive, as fighting escalates and civilians suffer.

The Israeli Army dropped thousands of leaflets over Gaza City on July 10 urging all residents to flee a heavy offensive that has rocked the main city of the besieged Palestinian territory.

The leaflets, addressed to "everyone in Gaza City", set out designated escape routes to the south and warned that the urban area, previously home to more than half a million people, would "remain a dangerous combat zone".

The warning follows three partial evacuation orders and came as Israeli troops, backed by tanks and aircraft, have fought Hamas and Islamic Jihad militants in the heaviest combat operations the city has seen in months.

In one operation, the Army said it had killed militants and found weapons inside the long-vacated Gaza City headquarters of the U.N. agency for Palestinian refugees, UNRWA.

Elsewhere across Gaza, deadly strikes have hit four schools used as shelters in four days, sparking international outrage.

The upsurge in fighting and displacement came as mediator Qatar was due to resume talks on Wednesday toward a truce and hostage release deal to end the war, now grinding on into its 10th month.

An Israeli delegation led by Mossad chief David Barnea arrived in Doha for the talks, a source with knowledge of the negotiations said, speaking on condition of anonymity because of their sensitivity.
