Iran unveils underground drone base amid warnings of retaliation against alleged assassination

In a television programme aired on May 28, 2022, the Iranian military unveiled a drone base located hundreds of metres under the Zagros mountain range. The base reportedly hosts 100 drones. Two new cruise missiles were also showcased; the Heidar-1 can be fired from a drone while the Heidar-2 can be launched from a helicopter. The unveiling followed the death of Revolutionary Guard Colonel Sayyad Khodai, who was killed on May 22, purportedly by the US and Israel. Iranian President Ebrahim Raisi said Tehran would avenge his death.
