Four coffins said to contain the remains of Israeli hostages have been received by Israel, as Palestinian prisoners and detainees were released in Gaza and the occupied West Bank in an overnight exchange as part of the fragile ceasefire deal.

Hamas says that it will return the bodies of four dead hostages on Thursday in exchange for Israel’s release of hundreds of Palestinian prisoners.

Palestinian teenagers and women detained by Israeli troops in Gaza were released back into the strip Thursday, marking the latest release during the ceasefire between Israel and Hamas. As they disembarked from the Red Cross buses in the southern town of Khan Younis, the teenagers looked gaunt and skinny. (AP video shot by Mohammad Jahjouh)
