A delicate truce between Israel and Hamas hangs by a thread after Israel blocked humanitarian aid into Gaza, in response to Hamas rejecting a new Israeli proposal to extend the ceasefire without any commitment to end the war or fully withdraw troops.

Israel wants to extend the first phase of the deal with Hamas, rather than begin negotiations over the more politically fraught second stage.

Officials from Israel, Qatar, Egypt and the United States have been involved in negotiations on the second phase in Cairo.
