Iran’s Intelligence Ministry confirmed on Thursday that five of the men involved in terror attacks in Iran had fought for the Islamic State in Iraq and Syria (ISIS).

A ministry statement said the men had left Iran to fight for the extremist group in Mosul, Iraq, as well as Raqqa, Syria — the group’s de facto capital. ISIS has claimed responsibility for the attack.

It identified the men only by their first names, saying they didn’t want to release their last names due to security and privacy concerns for their families.

The ministry also published pictures of their corpses.

Authorities earlier raised the death toll in the pair of attacks — against Iran’s parliament and the tomb of its revolutionary leader — to 16 people.

State television reported the increase, citing Ahmad Shojaei, the head of the country’s forensic centre.

Shojaei told state TV that “three of the victims are women.” He did not elaborate.

Iranian authorities have said assailants were Iranian nationals, adding they have arrested six suspects, including one woman, since the attack Wednesday in Tehran.

Separately, Iran’s foreign minister rejected U.S. statements about the attacks after President Donald Trump suggested the country bears some culpability for attacks in its capital.

Trump said “states that sponsor terrorism risk falling victim to the evil they promote.” He also said the U.S. was grieving and praying for the victims of the attacks.

Mohammad Javad Zarif called the comments “repugnant” and accused the U.S. of supporting terror. 

“The Iranian people reject such U.S. claims,” Zarif said via Twitter.
