Israel is studying Hamas' response to a proposal for a 60-day ceasefire and release of half the hostages still held in Gaza, two Israeli officials said, although one source reiterated that all Israeli captives must be freed for the war to end.

Egyptian Foreign Minister Bader Abdelattay said on Monday that his Qatari counterpart Sheikh Mohammed bin Abdulrahman Al Thani arrived in Cairo and joined talks on restarting ceasefire negotiations between Israel and the Palestinian militant group Hamas.
