US President Donald Trump says he’s “optimistic” a ceasefire deal in Gaza could be agreed next week after Hamas announced that it had “submitted a positive response” to a proposal for a 60-day truce with Israel.

Israeli airstrikes killed at least 38 Palestinians in Gaza, hospital officials told the Associated Press on Sunday, as Israel's military said it has struck over 100 targets in the embattled enclave in the past day.

U.S. President Donald Trump says Israel has agreed on terms for a new 60-day ceasefire with Hamas and that Washington would work with both sides during that time to try to end more than 20 months of war in Gaza.
