The United States is proposing a "bridge" plan to extend the ceasefire in Gaza into April beyond Ramadan and Passover and allow time to negotiate a permanent cessation of hostilities, the White House said in a statement on Friday.

The United States has put forward a new proposal that would secure the release of a handful of living hostages held by Hamas in exchange for a month-long extension of the Israel-Hamas ceasefire, a source familiar with the negotiations said.

Hamas says it has accepted a proposal from mediators to release one living American-Israeli hostage and the bodies of four dual-nationals who had died in captivity.
