Indonesian President Joko Widodo has pressed his US counterpart, Joe Biden, to take further steps to bring about a ceasefire in the conflict.

"Indonesia appealed to the US to do more to stop the atrocities in Gaza," Widodo said following talks at the White House on Monday.

"This [a ceasefire] is a must for the sake of humanity."

He earlier said he would bring Biden a “very strong message” from a joint summit of Arab and Muslim leaders over the weekend, which called for the fighting to end and condemned Israel.

Indonesia has the world's largest Muslim population.

Widodo also said ahead of his meeting with the US president that he would deliver a specific message to Biden from Palestinian leader Mahmoud Abbas.

The US has so far refused calls for a ceasefire, saying that would allow Hamas to regroup and attack again. It has, instead, been pushing for longer humanitarian pauses.
