Iran summoned the envoys of Great Britain, Denmark and the Netherlands on Saturday night, after a military parade shooting left 25 people dead, accusing them of harboring Iranian opposition groups in their countries, the state-run IRNA news agency reported.
“It is not acceptable that these groups are not listed as terrorist organizations by the European Union as long as they have not carried out a terrorist attack in Europe,” foreign ministry spokesman Bahram Qasemi was quoted as saying by IRNA.
Militants disguised as soldiers opened fire on an annual Iranian military parade in the country’s oil-rich southwest, killing at least 25 people and wounding over 60 in the deadliest terror attack to strike the country in nearly a decade.

The region’s Arab separatists, once only known for nighttime attacks on unguarded oil pipelines, claimed responsibility for the brazen assault and Iranian officials appeared to believe the claim.
Iranian Foreign Minister Mohammad Javad Zarif blamed regional countries and their “U.S. masters” for funding and arming the separatists, issuing a stark warning as regional tensions remain high in the wake of the U.S. withdraw from the Iranian nuclear deal.
“Iran will respond swiftly and decisively in defense of Iranian lives,” Zarif wrote on Twitter.
The attack came as rows of Revolutionary Guardsmen marched down Ahvaz’s Quds, or Jerusalem, Boulevard. It was one of many around the country marking the start of Iran’s long 1980s war with Iraq, commemorations known as the “Sacred Defense Week.”
