Hamas has said it has submitted a positive response to mediators about a ceasefire proposed by the US. The BBC has been told that it has requested some key changes but is prepared to enter negotiations ‘immediately’.

Israeli airstrikes killed at least 33 Palestinians in Gaza, hospital officials said on Sunday, as Israel's military said it has struck over 100 targets in the embattled enclave in the past day. The fighting came as Israeli Prime Minister Benjamin Netanyahu was preparing to fly to Washington for talks at the White House aimed at pushing forward ceasefire efforts.
