Ukraine used drones and missiles to take down an advanced Russian air-defence system worth US$1.2 billion early on Thursday, according to multiple reports.

The advanced S-400 “Triumf” air-defence system was destroyed in a joint operation by Kyiv’s security service (SBU) and navy, the BBC and Reuters reported, citing Ukrainian intelligence sources.

The attack off the coast of Yevpatoriya was orchestrated through the use of aerial drones and Neptune domestic missiles, per Anton Gerashchenko, a Ukrainian official writing on Telegram.

Yevpatoriya is a coastal city in the west of occupied Crimea, which Russia seized from Ukraine in 2014.
