Iran live updates: US blockade of Iran's Strait of Hormuz ports to begin Monday

Iranian Foreign Ministry spokesperson Esmaeil Baghaei said on Monday that a 15-point peace plan proposed by the U.S. to end the current conflict is unacceptable to Tehran.

Answering a question from the state-run news agency IRNA about reports of a new ceasefire plan during his weekly presser, Baghaei said, "A few days ago, they put forward proposals through intermediaries, and the 15-point U.S. plan was reflected through Pakistan and some other friendly countries."

"Right then we stated that such proposals are both extremely ambitious, unusual and illogical and not acceptable to us in any way," he said.

"Regardless of that proposal, we prepared the set of demands that we had and have based on our own interests and our own considerations," Baghaei said.

The Islamic Revolutionary Guard Corps' chief of intelligence, Majid Khademi, was killed in an attack overnight, the IRGC's public relations arm confirmed in a statement on Monday.

The IRGC statement blamed the "American-Israeli enemy" for Khademi's killing.

Khademi had been recently appointed to the role, replacing the previous intelligence chief -- Mohammad Kazemi -- who was killed in an Israeli attack in June during the 12-day war.

Israeli Defense Minister Israel Katz said in a statement on Monday that Israel was responsible for the assassination. Khademi, Katz said, was "directly responsible" for "war crimes and one of the three most senior figures" in the IRGC.

In a post to X, the Israel Defense Forces said Khademi was "one of the IRGC's most senior commanders and had accumulated extensive experience over many years."

The Sharif University of Technology has been hit by airstrikes, according to Iranian state media.

The strikes reportedly hit a gas station near the university gas station, causing a "temporary gas outage" in the Sharif neighborhood.

Iranian-American Rep. Yassamin Ansari, D-Ariz., denounced the reported overnight bombing in a post to X on Monday.

"Sharif University is Iran's MIT. They've produced a huge number of engineers who've gone on to Silicon Valley and founded some of the most successful American tech companies," Ansari wrote in her post. "Why are we bombing a university in a city of 10 million people?"

Sharif University is a leading public research institution and widely regarded as Iran's top university for science, engineering and technology.

Masoud Tajrishi, the university's president, condemned the attack in a video message sent from the scene of the incident, standing next to a pile of rubble outside a damaged building.
