Iran vows revenge as US submarine sinks warship, dozens killed

Iranian leaders have vowed retaliation against the United States following weekend attacks on Tehran carried out by U.S. and Israeli forces.

Ayatollah Abdollah Javadi Amoli, speaking on state television, said Iran was seeking to shed President Donald Trump’s “blood,” according to The Associated Press.

The attacks reportedly resulted in more than 1,000 Iranian casualties.

Iran’s Foreign Minister, Abbas Araghchi, condemned the military operations, accusing the United States of carrying out an “atrocity” in international waters.

“The U.S. has perpetrated an atrocity at sea, 2,000 miles away from Iran’s shores. Frigate Dena, a guest of India’s Navy carrying almost 130 sailors, was struck in international waters without warning,” Araghchi wrote on social platform X.

“Mark my words: The U.S. will come to bitterly regret [the] precedent it has set,” he added.

On Wednesday, a U.S. Navy submarine sank an Iranian warship in international waters using torpedoes. The vessel was carrying about 130 Iranian personnel. Sri Lankan authorities reported that 32 sailors were rescued, while 87 were confirmed dead.

The crew members were returning from a naval exercise led by India, in which the United States also participated.

The naval attack followed another strike on a girls’ primary school in Minab, Iran. Iranian officials described the incident as a violation of international law.

In a separate post on X, Araghchi said more than 160 girls were killed in the bombing.

“Their bodies were torn to shreds,” he wrote. “This is how ‘rescue’ promised by Mr. Trump looks in reality.”

“From Gaza to Minab, innocents murdered in cold blood,” he added.

Iran has since launched drone attacks on U.S. embassies in Riyadh, Saudi Arabia, and Kuwait. The country has also carried out strikes across the region, raising concerns about a wider conflict.

One attack on a civilian port in Kuwait reportedly killed six U.S. service members, while others were injured in a separate strike on Al Dhafra Air Base in the United Arab Emirates.

Despite the escalating tensions, U.S. Defense Secretary Pete Hegseth and President Trump have defended the ongoing military operation against Iran.
