IRGC will target US ships in Indian Ocean if fighting resumes, official says

President Donald Trump on Tuesday morning said in a post to social media that the U.S. has plentiful munitions, again dismissing reports that American forces have expended significant amounts of key weapons including anti-ballistic missile interceptors.

"The cowards and traitors would love to say the United States is low on munitions. It's not true. We have more munitions than we could ever possibly think of using, and are building them up now at levels we have never seen before," the president wrote.

Last week, a report from the Department of Defense Office of the Inspector General said the U.S. had experienced a shortfall in munitions due to Operation Epic Fury. 

"The Office of the Under Secretary for Acquisition and Sustainment (OUSW[A&S]) said that the munitions expenditure in OEF has resulted in strategic inventory shortfalls and revealed industrial base bottlenecks for munitions resupply," the report read, adding that the Pentagon was "working to streamline procurement processes and production lead times."

The Saudi General Directorate of Civil Defense on Tuesday issued a safety alert for the region of Najran, in the southwest of the kingdom close to the border with Yemen, where Saudi-backed government forces are fighting the Iran-backed Houthi rebels.

The safety alert was lifted shortly after it was announced, with the directorate saying in a post to X that the danger "has passed."

Iranian President Masoud Pezeshkian departed Tehran for the United Nations General Assembly in New York on Tuesday, the country's semi-official media outlets said, telling reporters he would "defend our positions with strength."

Referring to the ongoing conflict with the U.S. and the standoff centered on the Strait of Hormuz, Pezeshkian said, "Nations cannot be forced into submission through force," as quoted by the semi-official Tasnim News Agency.

Iranian Foreign Minister Abbas Araghchi will also be part of Tehran's delegation, having already arrived in New York on Monday, according to state media.

Hossein Mohebbi, a spokesman for the Islamic Revolutionary Guard Corps, told Iranian state TV Sunday night that “the war has not ended” and the IRCG is “prepared for a long-term war.”

Mohebbi added, “We will certainly change the geography of the war. There will be changes in the weapons and military equipment … and the world will see the power and precision of our weapons and the world will be astonished."

He also said Iran’s “targets are no longer necessarily the same as before.”
