The US State Department Spokesman Ian Kelly says that the US was not involved in the bombing of a mosque in southeastern Iran.

“We condemn this terrorist attack in the strongest possible terms and extend our sympathy to the families of those injured and killed,” Kelly said on Thursday.

“The US strongly condemns all forms of terrorism. We do not sponsor any form of terrorism in Iran,” Kelly added.

At least 25 people were killed and 125 others were injured on Thursday after bombers targeted a religious ceremony in the Shia Amir al-Mumineen Mosque.

Earlier on Friday, Deputy Governor, Jalal Sayah, told the Fars news agency that the three people arrested in connection with the bombing had been hired by the United States. This information came as a result of their initial interrogation.

Also on Friday afternoon, another senior Iranian official said that Israel and the US have had a hand in the mosque bombing that shook the southeastern city of Zahedan to its core.

“The bomb tragedy that occurred yesterday in the city of Zahedan is awash with Israeli and US fingerprints,” said Tehran’s Interim Friday prayer leader, Ayatollah Ahmad Khatami.
