Israel has said it will not release two Palestinian doctors, including paediatrician Hussam Abu Safiya, as part of the ceasefire deal, a Hamas official told CNN.

Safiya was beaten and kidnapped by Israeli forces in Gaza during a raid on Kamal Adwan Hospital in December last year after he refused to abandon patients under siege.

Footage in the aftermath of the attack showed Safiya wearing a white medical overcoat crossing a street strewn with rubble. Safiya has been held since then without charge.
