Jordanian Foreign Minister Ayman Safadi said on Sunday that the kingdom demanded an international investigation into what it said were many war crimes committed during Israel's military campaign in Gaza.
In remarks made during a press conference with the head of the UN Palestinian refugee agency (UNRWA), Safadi said those responsible for documented crimes should be brought to justice.
An Israeli airstrike killed 20 people in central Gaza, mostly women and children, and fighting raged across the north on Sunday as Israel's leaders aired divisions over who should govern Gaza after the war, now in its eighth month.
Prime Minister Benjamin Netanyahu has faced criticism from his own War Cabinet, with his main political rival, Benny Gantz, threatening to leave the government if a plan is not formulated by June 8 that includes an international administration for postwar Gaza.
The war has killed at least 35,000 Palestinians, according to Gaza's Health Ministry. Around 80% of the population of 2.3 million Palestinians have been displaced within the territory, often multiple times.
