Hamas said it sought a permanent ceasefire and a withdrawal of the Israeli military, prompting a rebuke from Steve Witkoff, President Donald Trump’s special envoy.

The ceasefire plan, which has been approved by Israeli officials, won a cool initial reaction Thursday from the militant group.

The latest friction in negotiations comes as the fighting nears 20 months of war, and as desperation grows among hungry Palestinians and relatives of hostages in Gaza.

ABC News takes a look at key dates and developments of Israel's actions in Gaza and the worsening humanitarian crisis since the temporary ceasefire with Hamas ended.

Meanwhile, the U.N. Food Program said 77 trucks carrying aid were stopped by hungry people who took the food before the trucks were able to reach their destination.

Israeli airstrikes killed at least 27 people in the Gaza Strip, hospital officials said Friday, while Hamas was reviewing a new Israeli-approved ceasefire proposal after giving it an initial cool response.

The proposal includes a 60-day ceasefire between Israel and Hamas in exchange for the release of some hostages in Gaza, Israeli officials said.

While the militant group says it will release 10 living and 18 deceased hostages still held in Gaza, there appear to be other details that need to be worked out before a ceasefire is declared.

Hamas has pushed for a permanent truce while Israel has held out for a temporary one. That wide gap has stymied efforts to end the war.
