Iranian Foreign Minister Mohammad Javad Zarif called on the US and Europe to stop funding and harboring terrorist groups that continue to kill innocent civilians and shamelessly claim responsibility for this, Tasnim reported.

“The west must cease financing and harboring terrorists. From their safe havens in the US and Europe, they promote hatred, agitate & organize murder & mayhem, and shamelessly claim responsibility for the murder of innocent Iranian civilians. Smokescreens can’t obscure this hypocrisy,” Zarif tweeted late on Saturday.

This tweet follows the announcement by the country's intelligence ministry about the arrest of the leader of a US-based terrorist group.

The ministry later explained that it had dealt a serious blow to the Tondar (Thunder) terrorist group, which carried out a terrorist attack in 2008 at a mosque in the city of Shiraz in Fars province. As a result of the terrorist attack, 14 people were killed, 215 people were injured.
