King Abdullah of Jordan met with US President Joe Biden on Monday and warned that an Israeli offensive in Rafah could result in a "new massacre" of Palestinian civilians.
The Israeli military had carried out airstrikes in Rafah and urged Palestinians to evacuate certain areas.
The Palestinian militant group Hamas had demanded an end to the war in exchange for releasing hostages, but Israeli Prime Minister Benjamin Netanyahu had rejected this proposal.
King Abdullah urged the international community to take urgent action to prevent the conflict from spilling over into the region.
Hamas attacked the Kerem Shalom crossing into Gaza, killing three Israeli soldiers.
Biden urged Netanyahu not to launch a large-scale military offensive in Rafah due to the risk of harming Palestinian civilians.
Jordan's King Abdullah warned of a potential new massacre if Israel proceeded with an offensive in Rafah, where 1.4 million Palestinians are displaced.
Both leaders emphasized the need for an immediate ceasefire.
The king and US president have reaffirmed their commitment to achieving a sustainable ceasefire in Gaza and delivering humanitarian aid due to the dire situation.
The Biden administration and Israeli officials are in disagreement over Israel's planned military operation in Rafah, where Palestinians were told to evacuate.
The US and Jordanian leaders discussed this issue, along with other challenges, during a recent White House meeting.
Jordan and other Arab states have been vocal in calling for a ceasefire due to increasing civilian casualties.
The text summarizes the start of the war between Israel and Hamas, which occurred on October 7, 2021.
During this raid, approximately 1,200 people were killed and 252 hostages were taken according to Israeli estimates.
Since then, over 34,600 Palestinians have been killed and over 77,000 have been wounded as a result of Israel's assault, according to Gaza's health ministry.
