The Iranian foreign minister warned of “uncontrollable consequences” for the U.S. if its backing of Israel’s war against Hamas in Gaza continues to expand.

“I say frankly to the American statemen who are now managing the genocide in Palestine that we do not welcome the expansion of the war in the region,” Foreign Minister Hossein Amir-Abdollahian said in a United Nations address. “But I warn, if the genocide in Gaza continues, they will not be spared from this fire. It is our home and West Asia is our region.”

Israeli airstrikes have killed more than 6,700 Palestinians, according to the Hamas-run Gaza Health Ministry.

At the start of the conflict, Hamas took about 200 people hostage, mostly Israeli civilians. Amir-Abdollahian said Hamas is ready to release those hostages and called on members to also support the freeing of about 6,000 Palestinians held in Israeli prisons.

Hostages have been the main focus of the conflict in the last week after four were released, two Americans and two elderly Israeli women.

Amir-Abdollahian held up the Hamas fighters as a Palestinian resistance and said the group has an “unalienable right” to self-determination and independence for Gaza, free from what he described as Israeli occupation of Palestine.

He also criticized the U.S.’s role in the decades-long conflict between Israel and Palestine.
