Israeli tanks surround north Gaza's Indonesian Hospital
Israeli tanks have reportedly encircled Gaza's Indonesian Hospital, where the Hamas-run health ministry said 12 people were killed on Sunday night.
The hospital's director, Dr Marwan Al-Sultan, told the BBC that the post-operative care department was hit and troops were only about 20m (66ft) away.
On Monday evening, he said intermittent shooting could still be heard on site.
The Israeli military said its forces targeted "terrorists" who had opened fire at them from within the hospital.
The head of the World Health Organization (WHO) said he was "appalled".
