Israeli soldiers close in on Gaza City, panic at hospitals where thousands had taken shelter

Israel has confirmed that its forces were operating close to Al-Shifa, the biggest hospital in Gaza City - they claim it is the site of the main command centre for Hamas, which is designated a terrorist organisation by the UK.

The Hamas-appointed Gaza health ministry says Israeli tanks have also surrounded two other hospitals - the Rantisi and the Al-Nasr.

Thousands more people have continued to flee the fighting to the south along the Salah Al Deen road - including many who had been sheltering at Al Shifa, where an explosion was reported in the courtyard.
