Under aerial bombardment from Israel, people sheltering in the south of the Gaza Strip after fleeing their homes earlier in the military offensive have said they have nowhere safe to go now, Reuters reports.

The city of Khan Younis is the focus of Israeli air strikes and artillery fire after fighting resumed on Friday following the collapse of a week-long truce. Its population has swelled in recent weeks as several hundred thousand people from the northern Gaza Strip have fled south.

Some are camping in tents, others in schools. Some are sleeping in stairwells or outside the few hospitals operating in the city.
