TEHRAN, Iran — Iran's paramilitary Revolutionary Guard said Monday that it launched ballistic missiles into eastern Syria, targeting militants the force blames for a recent attack on a military parade in Iran.

The launch was the Islamic republic's second such missile attack on Syria in over a year.

Iranian state television and the state-run IRNA news agency said the missiles "killed and wounded" militants in Syria, without elaborating. Syrian state media did not immediately acknowledge the strike.

The TV aired footage of one of its reporters standing by as one of the missiles was launched, identifying the area as being in Iran's western province of Kermanshah. A state TV-aired graphic suggested the missiles flew over central Iraq near the city of Tikrit before landing near the city of Abu Kamal, in the far southeast of Syria.

Abu Kamal is held by forces loyal to Syria's embattled President Bashar al-Assad. However, the city has been targeted even now by militants from the extremist Islamic State group, who have lost almost all the territory they once held in Syria and Iraq.

One missile shown on state television bore the slogans "Death to America, Death to Israel, Death to Al Saud," referring to Saudi Arabia's ruling family. The missile also bore in Arabic the phrase "kill the friends of Satan," referring to a verse in the Quran on fighting infidels.

"This is the roaring of missiles belonging to the Revolutionary Guard of the Islamic Revolution," the state TV's reporter said as the missiles launched behind him. "In a few minutes, the world of arrogance — especially America, the Zionist regime and the Al Saud — will hear the sound of Iran's repeated blows."

The semi-official Fars news agency, believed to be close to the Guard, identified the six missiles used as Zolfaghar and Qiam variants, which have ranges of 465 miles and 500 miles respectively.

Iran also launched drone attacks on the site afterward, state TV reported.

Analyst Hadi Seyed Afghahi, who is close to Iran's establishment and the Guard, said he believes the missiles were launched in coordination with the Syrian government.

The launch adds to confusion over who carried out the assault on a military parade in the Iranian city of Ahvaz on Sept. 22 that killed at least 24 people and wounded over 60.

Iran initially blamed Arab separatists for the attack in which gunmen disguised as soldiers opened fire on the crowd and officials watching the parade from a viewing platform in the southwestern city. Arab separatists also immediately claimed the attack and offered details about one of the attackers that ultimately turned out to be true.

The Islamic State group also claimed responsibility for the assault, but initially made factually incorrect claims about it. Later, IS released footage of several men that Iran ultimately identified as attackers, though the men in the footage never pledged allegiance to the extremist group.

In announcing the attack, Iranian state media said the missiles targeted both "takfiri" militants — a term it often applies to the Islamic State group — and Ahvazi separatists. The separatists have not been known to work with IS in the past.

In Monday's statement, the Guard said that based on evidence from the Ahvaz attack, the "terrorists" in eastern Syria are supported and guided by the United States in line with "satanic" plans of the White House, the Zionist regime — Iranian parlance for Israel — and a regional power, a reference to Saudi Arabia.

The statement added that the Guard's "iron fist" remains prepared for any further steps by Iran's enemies.
