ERBIL, Kurdistan Region of Iraq – Iran’s foreign ministry on Thursday condemned US attacks on southern and eastern parts of the country, including a rail route from Tehran to Mashhad, the city where the late supreme leader is to be buried nearly four months after he was killed in US-Israeli strikes.

The conflict between the US and Iran reescalated in earnest in the early hours of Wednesday, when they exchanged strikes targeting ports in southern Iran and US military bases in Kuwait and Bahrain, with both Washington and Tehran accusing each other of violating the ceasefire agreement.

They exchanged heavy fire for a second night in a row overnight into Thursday.

Soon after, Iran’s foreign ministry strongly condemned the attack.

“Undoubtedly constitute a gross war crime,” the ministry said, referring to the early Thursday attacks in the southern coastal provinces and two bridges in the eastern provinces on the railway leading to the holy city of Mashhad.

“The evil and psychopathic American ruling body has resorted to obscenity, lies, and military aggression.”

The body of late Iranian Supreme Leader Ali Khamenei was flown to Mashhad early Thursday for the burial ceremony, after being repatriated from processions held in Iraq’s holy Shiite cities of Najaf and Karbala.

On February 28, Khamenei, 86, from Mashhad, was killed in a US-Israeli strike on his compound in Tehran. He served as Iran’s highest political and religious authority for nearly 37 years, making him the country’s longest-serving leader since the 1979 Islamic Revolution.

Washington previously said that it would give Iran a “break” as funeral processions were being held for Khamenei, but later cited Iran’s overnight attacks on vessels in the Strait of Hormuz for the renewed strikes, with US President Donald Trump on Wednesday indicating that the peace deal between the two “is over" for him.
