Israel's move to cut all goods and supplies into the Gaza Strip has the support of the White House, according to a statement form the National Security Council.

UN Secretary General António Guterres, who has arrived in Cairo for Tuesday's emergency Arab summit on rebuilding Gaza, called for the "immediate" resumption of assistance. He urged "all parties to make every effort to prevent a return to hostilities".

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
