Washington: In his first public warning on Wednesday (local time), US President Joe Biden warned that he will stop supplying weapons if Israeli forces launch a major invasion in the southern Gaza city of Rafah, where more than a million Palestinians are taking refuge and thousands have been evacuated. Biden’s statement comes days after Israel launched a highly-opposed attack in Rafah, but the US President did not consider it a full-scale invasion as it did not strike any “population centres”.
