in Syria's Deir Az Zor province in retaliation for two deadly attacks in Tehran earlier this month that were claimed by the armed group.
"Medium-range missiles were fired from the (western)
provinces of Kermanshah and Kurdestan, and a large number of terrorists
were killed and weapons destroyed," the Guard said in a statement published on its Sepahnews website on Sunday. It said the attack targeted "a command base .. of the
terrorists in Deir Ezzor", using a different version of the name for the
province in eastern Syria. "The spilling of any pure blood will not go unanswered," it added.
The firing of the missiles, the first in 30 years outside
Iran's own territory, came hours after Supreme Leader Ayatollah Ali
Khamenei, in a statement on his website, vowed Iran would "slap its
enemies" in honour of the victims' families, including those killed in
Syria and Iraq.
The Islamic State (IS) claimed responsibility for the June 7
attacks on Iran's parliament and the Mausoleum of Ayatollah Khomeini
that left 17 people dead.
The attack on Khomeini's shrine was symbolically stunning. Khomeini was Iran's revolutionary leader in the 1979 ouster of the shah. Senior Iranian officials had also put the blame for the
Tehran attacks on Riyadh, saying Saudi Arabia was "promoting terrorist
groups" in Iran.
Iran is a key ally of the Syrian government
of President Bashar al-Assad, alongside Russia and the Iranian-backed
Hezbollah movement of Lebanon. In March, an official was
quoted by Iran's IRNA news agency as saying that about 2,100 combatants
sent by Iran have been killed in Syria and Iraq.
