May 8 (Reuters) - President Joe Biden on Wednesday publicly warned Israel for the first time that the U.S. would stop supplying it weapons if Israeli forces make a major invasion of Rafah, a refugee-packed city in southern Gaza.

“I made it clear that if they go into Rafah ..., I’m not supplying the weapons that have been used historically to deal with Rafah, to deal with the cities – that deal with that problem,” Biden said in an interview with CNN.

Biden's comments represent his strongest public language to date in his effort to deter an Israeli assault on Rafah while underscoring a growing rift between the U.S. and its strongest ally in the Middle East.
