The US has accused Hamas of privately making "impractical" demands while publicly backing a plan to extend the Gaza ceasefire. Washington wants the release of a US-Israel citizen and the bodies of four other hostages.

The United States has presented a "bridge" proposal to extend the Israel-Hamas ceasefire beyond Ramadan and Passover, allowing time to negotiate a permanent end to the conflict, the White House said in a statement.

Hamas on Friday said it agreed to release American-Israeli hostage Edan Alexander and the bodies of four other Americans, following a proposal from mediators to resume negotiations with Israel over a ceasefire in the Gaza Strip.
