Gaza's hospitals struggle with civilians

24 July 2014 Last updated at 23:56 BST

At least 13 people have been killed and more than 200 injured when a UN-run school used as a shelter in Gaza was apparently hit by a shell, officials say.

Hundreds of Palestinians were in the school in Beit Hanoun, where they were taking shelter from Israel's continuing military operation against Hamas rocket attacks.

More than 800 Palestinians and 35 Israelis have died since the Israel-Hamas conflict began on 8 July.

The BBC's Ian Pannell reports from the emergency unit in Gaza's main hospital as it deals with the growing number of casualties.
