Iran’s Foreign Minister on Thursday rejected United States’ statement about the attacks on Iran’s Parliament and the tomb of its revolutionary leader.

In a tweet, Mohammad Javad Zarif called the comments on the attack in Tehran a day earlier “repugnant” and accused the U.S. of supporting terror. The Islamic State group claimed responsibility for the attack, which, as of Thursday, killed 13, said the authorities.

President Donald Trump in a statement suggested that Iran bears some culpability for attacks in its capital.

Trump tweeted that “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.

Trump’s comments brought criticism from Iranians on social media, who recalled their government’s offers of support and the candlelight vigils held in Iran after the attacks of September 11, 2001 in the United States.

“Iranians lit candles for you on 9/11. You kick them while they’re down. Classy,” tweeted Ali Ghezelbash, an Iranian business analyst.

The US president has long accused Iran of backing terrorism and has threatened to tear up a 2015 nuclear deal between Tehran and major powers.
