U.S. President Joe Biden's plan to build a floating U.S. military port to speed up aid to Gaza could take up to 60 days to become a reality and involve more than 1,000 American troops, the Pentagon said on Friday.

The Pentagon offered the timeline a day after Biden announced the initiative in his State of the Union speech, as he seeks to cool anger in his Democratic Party over his staunch support for Israel's offensive in Gaza since Oct. 7.

The United Nations has warned that widespread famine in the Gaza Strip is "almost inevitable" without urgent action. A formal conclusion that famine has arrived in the coastal enclave of 2.3 million people could come next week. The U.N. has said that once famine is declared, it is too late to help many people.
