Iran threatens to avenge attack

DUBAI: Iran’s Revolutionary Guards vowed on Sunday to wreak "deadly and unforgettable" vengeance for a shooting attack on a military parade that killed 25 people, including 12 of their comrades, and Tehran accused Gulf Arab states of backing the gunmen.

Saturday’s assault, one of the worst ever against the elite force of the Islamic Republic, struck a blow at its security establishment at a time when the United States and its Gulf allies are working to isolate Tehran.

"Considering the Guards’ full knowledge about the centres of deployment of the criminal terrorists’ leaders..., they will face a deadly and unforgettable vengeance in the near future," the Guards said in a statement carried by state media.

Four assailants fired on a viewing stand in the southwestern city of Ahvaz where Iranian officials had gathered to watch an annual event marking the start of the Islamic Republic’s 1980-88 war with Iraq.

Soldiers crawled about as gunfire crackled. Women and children fled for their lives. Ahvaz National Resistance, an Iranian ethnic Arab opposition movement which seeks a separate state in oil-rich Khuzestan province, claimed responsibility for the attack.

Islamic State militants also claimed responsibility. Neither claim provided evidence. All four attackers were killed. There has been a blizzard of furious statements from top Iranian officials blaming the United States and Gulf kingdoms for the bloodshed and threatening a tough response.

"The Persian Gulf states are providing monetary, military and political support for these groups," President Hassan Rouhani said before leaving Tehran to attend a UN General Assembly meeting in New York.

Senior Guards commanders have said the Ahvaz attack was carried out by militants trained by Gulf states and Israel and backed by America. But it is unlikely that they will strike any of these foes directly.

The commanders could present a show of strength by launching missiles at groups operating in Iraq or Syria that may be linked to the militants who carried out the attack. They are also likely to enforce a tight security policy in Khuzestan province, arresting any perceived domestic opponents including civil rights activists.

Rouhani engineered Iran’s 2015 nuclear deal with world powers that ushered in a cautious detente with Washington before tensions flared anew with President Donald Trump’s decision to pull out of the accord and reimpose sanctions on Tehran.
