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.

Discussions of a ceasefire in Gaza have picked up in recent days. United States President Donald Trump said last week that Israel agreed to the conditions for a 60-day ceasefire, and negotiators could meet to carve out a path to finally ending Israel’s nearly 21-month-long war on Gaza.

Hamas said it is seeking an end to the war and the unrestricted entry of humanitarian aid as it is expected to announce a decision on a new U.S. ceasefire proposal to which U.S. President Donald Trump said Israel had agreed.
