Saudi Arabia has said that Israel's army operation in Rafah would cause a "humanitarian catastrophe".
It called for the United Nations Security Council (UNSC) to intervene, Hindustan Times reports.
This comes after Israeli Prime Minister Benjamin Netanyahu ordered the army to prepare to evacuate civilians from Rafah ahead of a planned ground operation in the city.
At least 28,064 Palestinians have been killed and 67,611 injured in Israeli strikes on Gaza since October 7, health ministry in Gaza told Reuters.
Saudi Arabia warns "of the extremely dangerous repercussions of storming and targeting" Rafah and affirmed its "categorical rejection and strong condemnation of their forced deportation", its foreign ministry statement said as per news agency AFP.
"This continued violation of international law and international humanitarian law confirms the necessity of convening the Security Council urgently to prevent Israel from causing an imminent humanitarian catastrophe," the statement added.
Rafah is overcrowded as more than one million displaced Palestinians have taken refuge in the city located in Gaza's far south.
Saudi Arabia has never recognised Israel but had considered doing so before the Israel-Hamas war broke out. Riyadh has repeatedly called for a ceasefire while criticising Israeli "aggression" in Gaza.
Saudi Arabia also said this week it had told Washington it would not establish ties with Israel until an independent Palestinian state is “recognised”.
Israeli forces should leave Gaza, Riyadh reportedly told Washington.
