Tasnim� The Islamic Revolution Guards Corps (IRGC) Public Relations Department said more than 170 Daesh (ISIL) terrorists, including several ringleaders, have been killed in its recent missile attack on terrorist sites in Syria�s eastern province of Deir ez-Zor.

In a statement released late on Wednesday, the IRGC Public Relations Department described the recent operation, code-named �Laylat al-Qadr�, as successful and said it inflicted heavy casualties on the terrorists in Syria.

�Over 170 Takfiri terrorists, including several of their commanders and ringleaders, were killed and in addition to injuring many others... (it caused) the destruction of their (military) equipment, gears and systems,� the statement read.

The IRGC further emphasized that the operation was carried out under the command of Ayatollah Seyed Ali Khamenei, Commander-in-Chief of the Iranian Armed Forces.

In the operation on Sunday night, the IRGC fired six mid-range ballistic missiles at various targets within a range of 650 to 700 kilometers, including the headquarters, ammunition and logistic depots of the terrorists.

Speaking to the Tasnim News Agency, Head of the IRGC Public Relations Department General Ramezan Sharif said, �The firing of these missiles had previously been coordinated with Syria.�

He added that the missile attacks were carried out in response to the recent Daesh-claimed terror attacks in Tehran, adding that Zolfaqar high-precision missiles were among those used in the attack.

The IRGC public relations office statement said Sunday that the missiles were fired from the IRGC aerospace force�s bases in Iran�s western provinces of Kermanshah and Kurdistan.
