FNA- Iranian Foreign Ministry Spokesman Bahram Qassemi lauded the Islamic Revolution Guards Corps' efforts to eradicate terrorist groups in the region, and said the IRGC will powerfully continue its fight against terrorism.

"The Islamic Republic of Iran has doubt about uprooting terrorism, insecurity and instability in the region and will fight against these ugly and disgusting plights with all its power," Qassemi said on Wednesday.

"To this end, the proper and effective moves of the Islamic Republic of Iran's Armed Forces, specially the IRGC, in its relentless fight against the Takfiri and terrorist streams in the region will continue with no respect for the prates of those who support the criminal terrorists," he added.

His remarks came days after the IRGC launched multiple missile strikes at the ISIL centers in Syria's Deir Ezzur from bases in Western Iran in retaliation for the June 7 twin terrorist attacks in Tehran.

"The Takfiri terrorists' command center, concentration points and logistical centers used for assembling cars for suicide attacks in Deir Ezzur region in Eastern Syria came under attack by the IRGC moments ago in a move to punish the terrorists for the twin attacks on the Iranian parliament and the holy shrine of the late founder of the Islamic Republic, Imam Khomeini, on June 7," a statement issued by the IRGC Public Relations Office said.

"A number of mid-range ground-to-ground missiles fired from the IRGC Aerospace Force bases in Kermanshah and Kurdistan provinces targeted the Takfiri terrorists in this operation and struck them with lethal and crushing blows," the statement said.

The statement further added that according to intel and reports, "a large number of Takfiri terrorists have been killed and their equipment, systems and weapons have been destroyed" in the operation.

The IRGC cautioned that the missile strikes were just a warning to deter any further action by the terrorists. "The IRGC warns the Takfiri terrorists and their regional and trans-regional supporters that they would be engulfed by its revolutionary wrath and flames of the fire of its revenge in case they repeat any such devilish and dirty move in future."

An hour later, the IRGC put the number of the missiles at 6, and said that they flew through Iraq's airspace.

Three unknown assailants fired several rounds at the guards protecting the parliament building in Tehran on June 7. The assailants opened their way into the parliament's administrative building while shooting at the guards and civilians.

A similar attack took place at the holy shrine of the late founder of the Islamic Republic, Imam Khomeini, parallel with the parliament attack.

A sum of 18 people, including a parliament guard, were killed and 52 others were wounded in the twin attacks claimed by the ISIL.
