The Israeli Defence force has released a video that it says shows evidence Hamas held hostages under a specialist children's hospital in central Gaza.
The video, filmed in the basement of the Al-Rantisi Hospital, shows a cache of ammunition, grenades and suicide vests along with a rope tied around the base of a chair and a motorcycle riddled with bullet holes.
Items of womens clothing and a baby's bottle were also found.
It comes amid reports Hamas is asking for a five day truce in exchange for up to 70 hostages.
CNN's Jeremy Diamond is in Sderot just a kilometre from the Gaza border.
