Iran’s Foreign Minister has warned of serious consequences to follow an Israeli planned ground assault into the southern Gaza Strip city of Rafah.

Hossein Amir-Abdollahian made the remark in a Monday post on X social media platform.

"The expansion of the occupying Israeli regime’s war crimes and genocide to include Palestinian refugees in Rafah will have serious consequences for Tel Aviv," he said.

His comment came after earlier in the day, at least 100 civilians, mostly women and children, were killed and nearly 230 others wounded in extensive air raids and artillery strikes by the Israeli regime against Rafah.

The aggression came as more than 1.4 million people, about five times Rafah's usual population, have fled to the city amid Israel's genocide in the Gaza Strip, which has killed upwards of 28,300 Palestinians since its commencement on October 7, 2023.

Israeli prime minister, Benjamin Netanyahu, ordered the Israeli military on Friday to prepare to evacuate civilians from Rafah ahead of a planned ground operation against the city. Aid organizations, however, say such a move will be nearly impossible, given the scale of devastation elsewhere in Gaza and the huge number of people trapped in the besieged area.

Iran's foreign minister also met with his Qatari counterpart, Mohammed bin Abdulrahman bin Jassim Al Thani, on Monday.

Amir-Abdollahian is currently in Doha on the third leg of a regional tour, which has already taken him to Lebanon and Syria.

Also on Monday, Iranian Foreign Ministry's spokesman Nasser Kan'ani warned that the Israeli regime's aggression against Rafah and a ground invasion of the city could result in "another humanitarian catastrophe and war crime against the defenseless Palestinian people."

He added that invasion of Rafah is not only in conflict with and disruptive of ongoing talks on a potential ceasefire, but also contravenes an interim ruling by the International Court of Justice, which ordered Israel last month to act immediately to prevent genocide in Gaza.

Such an invasion, Kan'ani said, serves as "a proof to sinister intentions of Zionists who have repeatedly violated all the international legal norms with the purpose of discrediting them."

“If the United States and other Western allies of Zionists are honest in their expressions of concern about the security and stability of the region, it is now time to take immediate action to put a leash on the maniacal behavior of the Zionist regime’s officials who are massacring the defenseless people of Palestine,” the spokesman said.

Kan'ani then drew the attention of international organizations, governments, and the world's public opinion to the concerning consequences of the Israeli regime's military aggression against Rafah.
