FNA- Lieutenant Commander of the Islamic Revolution Guards Corps (IRGC) Brigadier General Hossein Salami underlined that the Wednesday terrorist attacks in Tehran were the outcome of a trilateral project by Washington, Tel Aviv and Riyadh.

"The joint Saudi-Israel-US project was aimed at striking a blow at Iran’s political and security power," Brigadier General Salami said.

General Salami hailed the effective response to the attacks, and said it “buried our enemies’ political dream alive, showing that Iran will be a graveyard for anyone seeking to endanger its security".

He said the acts of terror were perpetrated as a result of the enemies’ back-to-back defeats in regional disputes and proxy warfare over the past years.

Four unknown male assailants attacked the parliament building in Iranian capital, killing and scores of people in the hallway on Wednesday morning. Also, another group of terrorists raided the holy shrine of the late founder of the Islamic Republic, Imam Khomeini, South of the Tehran on Wednesday morning, killing and wounding tens of people in a bomb attack and a shooting spree.

“While the Americans, the Saudis, some reactionary regional countries and Westerners were trying to tip the regional equations in their own favor and threaten the Islamic Republic’s establishment, they didn’t manage to act out their plans in Syria and Iraq, and suffered defeat in regional political disputes,” he added.

“The Saudis’ regional policies have completely been defeated, while Daesh’s turf has dwindled and is on the verge disappearance,” he added in reference to accusations against Riyadh of funding and fueling Takfiri terrorism in the region.

When it comes to the country’s national security, Salami said, Iran does not “joke” with any side.

“We are extraordinarily powerful. We have everything at our disposal and enjoy a variety of options,” said the Iranian commander, warning that “if anyone seeks to disrupt our national security, we won’t leave him any safe spot.”

The IRGC forces killed all the four terrorists who attacked the parliament building on Wednesday morning, bringing the situation under control after several hours of clashes on evening.

Last month, US President Donald Trump went to Saudi Arabia in his first foreign visit, clinching a USD-110-billion arms deal with Riyadh, which US Secretary of State Rex Tillerson said was aimed at “countering” Iran.

Trump then travelled to Israel. In both places, he referred to Iran as a purveyor of terrorism and urged the Persian Gulf Arab states to unite against the Islamic Republic, endorsing both Riyadh and Tel Aviv’s anti-Iran stance.

Tehran has consistently rejected such accusations of intervention in regional affairs, and urged dialog and convergence among the Persian Gulf littoral states.
