President Joe Biden spoke to Israeli Prime Minister Benjamin Netanyahu on Sunday, impressing upon the Jewish state leader that no military operation in Rafah should continue without a plan to evacuate civilians.

Biden “called for urgent and specific steps to increase the throughput and consistency of humanitarian assistance to innocent Palestinian civilians,” the White House said in a statement Sunday afternoon. “He reaffirmed his view that a military operation in Rafah should not proceed without a credible and executable plan for ensuring the safety of and support for the more than one million people sheltering there.”
