DUBAI, United Arab Emirates (AP) Several officials in the Middle East and the U.S. believe the level of devastation in the Gaza Strip caused by a nine-month Israeli offensive likely has helped push Hamas to soften its demands for a cease-fire agreement.

Hamas over the weekend appeared to drop its longstanding demand that Israel promise to end the war as part of any cease-fire deal. The sudden shift has raised new hopes for progress in internationally brokered negotiations.

Israeli Prime Minister Benjamin Netanyahu on Sunday boasted that military pressure including Israels ongoing two-month offensive in the southern Gaza city of Rafah is what has led Hamas to enter negotiations.

Hamas, an Islamic militant group that seeks Israels destruction and took control of Gaza in 2007, is highly secretive and little is known about its inner workings.

But in recent internal communications seen by The Associated Press, messages signed by several senior Hamas figures in Gaza urged the groups exiled political leadership to accept the cease-fire proposal pitched by U.S. President Joe Biden .

The messages, shared by a Middle East official familiar with the ongoing negotiations, described the heavy losses Hamas has suffered on the battlefield and the dire conditions in the war-ravaged territory. The official spoke on condition of anonymity to share the contents of internal Hamas communications.

It was not known if this internal pressure was a factor in Hamas flexibility. But the messages indicate divisions within the group and a readiness among top militants to reach a deal quickly, even if Hamas top official in Gaza, Yahya Sinwar , may not be in a rush. Sinwar has been in hiding since the war erupted last October and is believed to be holed up in a tunnel deep underground.
