TEHRAN, Young Journalists Club (YJC) - IRGC spokesman Brigadier General Ramezan Sharif made the remarks in an exclusive interview with Press TV on Monday.
Late Sunday, the IRGC fired six medium-range ballistic missiles at Daesh targets in Syria's Dayr al-Zawr in response to a June 7 attack by the Takfiri terror outfit against two locations in Tehran, which killed 18 people.
Sharif reminded that the counterstrike had taken place “on a very limited scale."
“If similar behavior is repeated with similar terrorist operations, more serious revenge will be exacted on them by our missile power and also by our forces against terrorists,” he cautioned.
“The message of this operation for terrorist groups and also their regional and international sponsors is that they should never try to undermine the national security of Iran,” he noted.
“Fortunately, all incoming reports and images of drones which were monitoring the operation suggest that the six medium-range powerful Iranian missiles have precisely hit the targets, the key bases of terrorists in the general area of Dayr al-Zawr inside Syria.”
He said field reports gleaned by the IRGC suggested that the attack had inflicted considerable casualties on terrorist groups and destroyed their equipment and systems.
The retaliation, he said, came after the IRGC vowed to retaliate against the terror assaults.
“As the Leader said, they will receive a slap in the face,” Sharif asserted, echoing Sunday's remarks by Ayatollah Seyyed Ali Khamenei.
