DEIR al-BALAH, Gaza Strip — Hamas said Friday it has given a “positive” response to the latest proposal for a ceasefire in Gaza but said further talks were needed on implementation.

It was not clear if Hamas’ statement meant it had accepted the proposal from U.S. President Donald Trump for a 60-day ceasefire. Hamas has been seeking guarantees that the initial truce would lead to a total end to the war, now nearly 21 months old. Trump has been pushing hard for a deal to be reached, and Israeli Prime Minister Benjamin Netanyahu is due to visit the White House next week to discuss a deal.

The Hamas statement came as Israeli airstrikes killed 15 Palestinians in Gaza early Friday, while a hospital said another 20 people died in shootings while seeking aid.

The U.N. human rights office said it has recorded 613 Palestinians killed within the span of a month in Gaza while trying to obtain aid. Most were killed while trying to reach food distribution points run by an Israeli-backed American organization, while others were massed waiting for aid trucks connected to the United Nations or other humanitarian organizations, it said.

Efforts ongoing to halt the war

Trump said Tuesday that Israel had agreed on terms for a 60-day ceasefire in Gaza, during which the U.S. would “work with all parties to end the war.”

He urged Hamas to accept the deal before conditions worsen.

In its statement late Friday, Hamas said it “has submitted its positive response” to Egyptian and Qatari mediators.
