Tehran, Jun 19 (IANS): Iran's Islamic Revolution Guards Corps (IRGC) announced here that its aerospace units have targeted the "terrorists" command centers in Syria's Deir ez-Zor with its missiles.

The missile attack on Sunday aimed to punish the "Takfiri terrorists" for their recent twin attacks in Iran's capital Tehran, the IRGC's Public Relations said in a statement.
