Israel has introduced what it said was a new U.S. ceasefire plan and is trying to force Hamas to accept it by imposing a siege on the Gaza Strip.

The move came hours after Israel had proposed a temporary extension of the truce, though one with terms that Hamas is unlikely to accept.

Israel will stop the entry of all humanitarian aid into Gaza to pressure Palestinian militant group Hamas into accepting a temporary extension of the ceasefire agreement, officials said on Sunday, a day after the initial phase of the truce expired.
