Countries including the United States, Canada, Russia and Arab states have pushed for either a pause or cease-fire in fighting between Israel and Hamas in the Gaza Strip so that humanitarian aid can be delivered to besieged Palestinian civilians, and late on Tuesday eight trucks with water, food and medicine entered the enclave from Egypt.

Nearly three weeks after Hamas militants shocked Israel with an attack on southern Israeli towns in a rampage that killed 1,400 mostly civilians, world leaders sought to prevent the conflict from spreading.

U.S. President Joe Biden and Saudi Arabian Crown Prince Mohammed bin Salman spoke by phone on Tuesday and agreed on broader diplomacy "to maintain stability across the region and prevent the conflict from expanding," the White House said.
