Iran live updates: Iran accuses US of violating MOU

Former IRGC commander Maj. Gen. Mohsen Rezaei said in an interview with Iranian state media on Friday that if the U.S. continues its military actions against Iran, Tehran will move to an offensive position rather than a retaliatory one.

"If America continues the war in the coming days, Iran will move from the phase of retaliation to the offensive phase, and we declare that the conditions for both negotiations and war are over," the general said.

The IRGC general further stated Washington had violated all five preliminary clauses of the MoU, and that the "prediction that Donald Trump would tear up the memorandum of understanding came true."

Fars News Agency also reports the general saying if America continues the war in the next two to three days, Iran will enter the stage of "full-scale assault and annihilation."

The U.S. announced another round of strikes on Iran on Friday for the seventh consecutive night, according to U.S. Central Command.

"The strikes are designed to continue degrading Iranian military capabilities at the Commander in Chief's direction," CENTCOM said.

The U.S. also redirected four commercial vessels, disabled one and boarded on in its naval blockade on Iran, CENTCOM said.

U.S. Central Command released video of a U.S. airstrike that it says destroyed a port surveillance tower that has been used by Iran's Islamic Revolutionary Guard Corps "to track and target commercial vessels transiting the Strait of Hormuz."

Iran has previously described the tower as a civilian structure.

"On July 16, U.S. forces successfully destroyed the Chah Bahar Shahid Kalantari Port surveillance tower, part of a maritime surveillance network along Iran’s Gulf of Oman coastline used for decades by the Islamic Revolutionary Guard Corps (IRGC) to track and target commercial vessels transiting the Strait of Hormuz," CENTCOM said.

"The destruction of the tower directly degrades IRGC’s ability to coordinate attacks on innocent civilian crew members. Furthermore, the strike protects freedom of navigation in regional waters for all vessels, except for ships attempting to violate the ongoing U.S. naval blockade against Iran," CENTCOM said.

Iran claims it targeted a U.S. military base in eastern Syria on Friday, which would be the first known attack by Iranian forces on Syrian territory since the U.S. and Israel jointly launched a war against Iran earlier this year.

Iran's Islamic Revolutionary Guard Corps said it carried out a "surprise attack" on a U.S. special operations command center at al-Tanf near Syria's southeastern borders with Iraq and Jordan in response to the killing of Iranian soldiers in the southeastern Iranian city of Iranshahr, according to Iran's state broadcaster IRIB. ABC News cannot independently verify the claim.

In February, the U.S. military said it had completed a withdrawal from the so-called al-Tanf Garrison, which "was a key base along a southern highway that was a main smuggling route for Iranian weapons flowing into Syria and particularly Hezbollah in Lebanon."
