Iran live updates: 7th killed service member is identified

President Donald Trump submitted to Congress on Monday a war powers notification regarding military action taken on Feb. 28 against the government of Iran.

"Despite my Administration's repeated efforts to achieve a diplomatic solution to Iran's malign behavior, the threat to the United States and its allies and partners became untenable," Trump wrote in a letter addressed to Sen. Chuck Grassley, president pro tempore of the Senate.

"Accordingly, and at my direction, on February 28, 2026, United States forces conducted precision strikes against numerous targets within Iran including ballistic missile sites, maritime mining capabilities, air defenses and command and control capabilities. Strikes were undertaken to protect United States forces in the region, protect the United States homeland, advance vital United States national interests including ensuring the free flow of maritime commerce through the Strait of Hormuz and in the collective self-defense of our allies, including Israel," Trump wrote.

In the notification, Trump acknowledges that "it is not possible at this time to know the full scope and duration of military operations that may be necessary" during this conflict.

"United States forces remain postured to take further action, as necessary and appropriate to address further threats and attacks upon the United States or its allies and partners," Trump wrote.

The U.S. embassy in Riyadh, Saudi Arabia, has been struck by two Iranian drones, according to two U.S. officials and initial estimates from the Saudi Ministry of Defense.

The embassy was relatively empty given the overnight hours and no one is believed to have been injured -- but there is still believed to be an ongoing threat to the embassy, the U.S. officials said.

The strikes resulted in "limited fire and minor damage to the building," a spokesperson for the Saudi Ministry of Defense said.

The State Department also issued an alert advising Americans in Saudi Arabia to shelter in place immediately.

This is the second U.S. embassy to sustain damage in an Iranian drone strike, following Kuwait on Monday.

Iranian Foreign Minister Abbas Araghchi said he believes American bases are "legitimate targets" in a new interview with Iranian state TV.

"When the United States attacks us -- whether by fighter jets or the ships it deploys -- they have access to our territory to strike with all kinds of missiles and aircraft. We cannot reach their territory, but we can reach their bases. I think those bases are legitimate targets," Araghchi said.

An Islamic Revolutionary Guard Corps commander said the Strait of Hormuz is "closed."

"The strait is closed, and whoever wants to cross, our heroes in the navy of the IRGC and army will set those ships on fire," Brigadier General Ebrahim Jabari said on Iranian state TV earlier.

The Strait of Hormuz is one world's most important chokepoints for oil. Roughly 20% of the world's oil passes through the Strait, according to the U.S. Energy Information Administration.
