Aug. 9 (UPI) — Iran has replaced its top security official with another commander of its powerful Islamic Revolutionary Guards Corps, a spokesman for President Masoud Pezeshkian said late Sunday.

Mohsen Rezaei, who had been an adviser to Supreme Leader Ayatollah Mojtaba Khamenei, will be the new secretary of the Supreme National Security Council. He replaced Mohammad Bagher Zolghadr, who resigned.

Zolghadr had been in the post since his predecessor, Ali Larijani, was killed in an Israeli air strike in March. He will serve as political adviser to Khamenei.

The shakeup came as Foreign Minister Abbas Araghchi said Iran is not talking directly with the U.S. to end the war with Tehran and open the Strait of Hurmuz, despite claims by U.S. officials that the sides are near a deal.

Araghchi was quoted by the Mehr news agency as saying that “messages are being exchanged through intermediaries” and Iran isn’t talking directly with Washington. He reportedly added Washington must meet conditions by Iran if a deal is reached with Oman to open a trade route through the waterway.

U.S. President Donald Trump told Axios on Sunday his administration is “low keying it” in negotiations with Tehran.

“We are only semi-negotiating with them. We are just watching Iran with its huge inflation and the fact they have no money,” Trump said. “It will work out. It always works out. It’s like a chess game.”

Iran’s Supreme National Security Council and Khamenei would have to agree to any deal to open the strait.

On Saturday, Zolghadr said U.S. forces should be withdrawn from near Iran. He added that the U.S. should compensate Iran for war damages as well as lift sanctions.

Iranian diplomats said earlier last week that Tehran and Oman were near a new agreement to manage the strait.
