DUBAI, Sept 23, (Agencies): Iran’s Revolutionary Guards vowed on Sunday to exact “deadly and unforgettable” vengeance for a shooting attack on a military parade that killed 29 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.

Meanwhile, His Highness the Amir Sheikh Sabah Al-Ahmad Al-Jaber Al-Sabah on Saturday sent a cable to President of the Islamic Republic of Iran Hassan Rouhani, to express sincere condolences on the deadly assault on a military parade in the Iranian city of Ahvaz.

In his cable, His Highness the Amir condemned the terrorist attack which left dozens of casualties. He prayed for the victims and wished speedy recovery and wellness for the injured. His Highness the Crown Prince Sheikh Nawaf Al-Ahmad Al-Jaber Al-Sabah and His Highness the Prime Minister Sheikh Jaber Al-Mubarak Al-Hamad Al-Sabah sent similar cables of condolences to the Iranian president.

National Assembly Speaker Marzouq Al-Ghanim also sent a cable to Iranian counterpart Ali Larijani to offer condolences on the deadly attack. In his cable, Al-Ghanim condoled with families of the victims and denounced the terrorist act. He also prayed for the dead and wished the wounded speedy recovery.

“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, including President Hassan Rouhani, accusing Iran’s adversaries the United States and Gulf kingdoms of provoking the bloodshed and threatening a tough response.

Nikki Haley, US Ambassador to the United Nations, rejected Rouhani’s accusations as rhetoric. “He’s got the Iranian people … protesting, every ounce of money that goes into Iran goes into his military, he has oppressed his people for a long time and he needs to look at his own base to figure out where that’s coming from,” Haley told CNN. “He can blame us all he wants. The thing he’s got to do is look in the mirror,” she said.

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

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

Three Arab activists told Reuters that security forces, especially the intelligence branch of the Revolutionary Guards, had detained more activists in Ahvaz. “There are many checkpoints on the streets of Ahvaz, and the security forces are searching cars,” said Hossein Bouazar, a member of Ahwazi Centre for Human Rights. “Many people are scared.” Reuters could not immediately verify this account.

Iran has also been hit by sporadic street protests over economic hardship that have taken on anti-government overtones. Rouhani engineered Iran’s 2015 nuclear deal with world powers that ushered in a cautious detente with Washington before tensions flared anew with US President Donald Trump’s decision in May to pull out of the accord and reimpose sanctions on Tehran.

The attack on the military parade is likely to give security hardliners like the Guards more political ammunition because they did not endorse the pragmatist Rouhani’s pursuit of the nuclear deal with the West, analysts say. In New York, Trump’s personal lawyer Rudy Giuliani said on Saturday that US sanctions were inflicting economic pain on Iran that could lead to a “successful revolution”.

The Trump administration has said that changing Iran’s system of government is not US policy. Shi’ite Iran is at odds with Western-allied Sunni Muslim Saudi Arabia for predominance in the Middle East. The regional superpowers support opposing sides in the civil wars in Yemen and Syria as well as rival political groups in Iraq and Lebanon.

Iran’s Foreign Ministry summoned the United Arab Emirates’ charge d’affaires on Sunday over comments made about the bloody fusillade at the military parade, state-run PressTV said. There was no immediate comment from Saudi Arabia on Rouhani’s allegations. Iran denies Gulf Arab accusations that it seeks to extend its sway via proxies around the Middle East, calling for states in the oil-producing region to guarantee its security without the interference of the United States and other Western powers. A senior United Arab Emirates official denied on Sunday Iranian allegations alluding to the involvement of the UAE in training troops that claimed the attack.

The “formal incitement against the UAE from within Iran is unfortunate, and has escalated after the Ahvaz attack,” said Minister of State for Foreign Affairs for the United Arab Emirates Anwar Gargash in a tweet. “The UAE’s historical position against terrorism and violence is clear and Tehran’s allegations are baseless.” Giuliani, told members of Iran’s self-declared government in exile on Saturday that the US sympathizes with their efforts to overthrow that country’s official government.

The former New York mayor spoke to members and supporters of the National Council of Resistance of Iran, the biggest opposition group to Iran’s Islamic regime. Two USbased members who joined the gathering have been targeted for assassination by alleged Iranian agents named last month in criminal complaints issued by the US District Court for the District of Columbia.

“So I say to the Iranian government, you must truly be afraid of being overthrown,” Giuliani said. “We will not forget that you wanted to commit murder on our soil.” Giuliani said the Paris-based opposition organization is the democratic answer to an Iranian regime he called “a group of outlaws and murderers and people who pretend to be religious people and then have so much blood on their hands it’s almost unthinkable.” Instead, Giuliani said, “Iran is entitled to freedom and democracy.”
