ERBIL, Kurdistan Region of Iraq – The Iranian army said Wednesday that seven of its members were killed in the southeastern Sistan-Baluchistan province following what it said were 13 US missile strikes, as the government said the overall death toll had risen to 30.

Washington and Tehran traded daily strikes for almost a week, leading US President Donald Trump on Wednesday to say that the US-Iran peace deal “is over,” merely 21 days after the memorandum of understanding was signed.

The Iranian Army said early Wednesday that the US has allegedly “ fired 13 missiles” at one of its bases in Sistan-Baluchistan’s Bampour.

“During this attack by the terrorist US Army, seven career and conscript personnel of the 388th Brigade of Iranshahr attained martyrdom, and a number of personnel were wounded and are currently receiving treatment,” the army said. 

The attack struck a sanatorium, guesthouse, and guard posts at the facility, with the army accusing the US of aiming to inflict "the greatest human casualties,” while warning of retaliation. 

US strikes have largely targeted southern Iran near the Strait of Hormuz, while Iran has resumed targeting countries hosting US military bases and also attacked vessels for allegedly failing to provide prior notification before transiting the waterway.

“In the recent attacks on the southern part of the country, more than 30 civilians lost their lives,” Iranian government spokesperson Fatemeh Mohajerani said on Wednesday.

Since the start of the conflict in late February, Tehran has restricted access to the Strait of Hormuz, a key waterway responsible for the transport of roughly 20 percent of the world’s oil.

Late Tuesday, the US Central Command (CENTCOM) announced that it had resumed the naval blockade against vessels transiting to and from Iranian ports.

The US had repeatedly stressed free navigation in the vital waterway as one of its main demands before the MoU was reached with Iran, but Trump on Monday announced that Washington will now protect ships transiting Hormuz in return for charging 20 percent on all cargo shipped.
