US President Donald Trump has voiced confidence that a ceasefire deal in Gaza could be agreed this week after Hamas announced that it had “submitted a positive response” to a proposal for a 60-day truce with Israel.

Israeli Prime Minister Benjamin Netanyahu is in Washington Monday to meet U.S. President Donald Trump, who has been pushing for a ceasefire that might lead to an end to the 21-month war in Gaza. Israel and Hamas are considering a new U.

Israel and Hamas are believed to have agreed that 10 living hostages and the remains of 18 others should be freed during the first 60 days of a cease-fire, but they have not reached a consensus on how many Palestinian prisoners should be released during the same period. Up to 20 hostages are still thought to be alive.
