US President Joe Biden has threatened Israel with further restrictions on the supply of military equipment were Israel to carry out a major military offensive in the southern Gaza city of Rafah.

"I made it clear that if they (Israel) 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 told broadcaster CNN in an interview, stressing "they haven`t gone in Rafah yet".
