U.S. President Joe Biden will launch a renewed drive Wednesday for a Gaza ceasefire and hostage release deal, now that Israel and Hezbollah have agreed to a truce in Lebanon, his national security adviser said.

The truce that began before dawn Wednesday in the south Lebanon war means Iran-backed Hezbollah is no longer fighting in solidarity with Hamas in Gaza. That will increase pressure on the militant Palestinian group to agree to a ceasefire and hostage deal, Jake Suillivan told MSNBC.
