Israeli forces pushed toward the heart of Gaza City on Wednesday as pressure mounted on U.S. President Donald Trump to find a way to end nearly two years of fighting in Gaza and secure the release of Israeli hostages held there.

U.S. special envoy Steve Witkoff said the U.S. is "hopeful ... even confident that in the coming days we'll be able to announce some sort of breakthrough" on the war in Gaza.

He said Trump's 21-point peace plan had been presented to some leaders on Tuesday on the sidelines of the U.N. General Assembly.
