According to Al-Masdar News, the Houthi rebels reportedly announced the successful launch of a variant of Russian Scud-type missile known as Borkan-1 at around 8:00 p.m. GMT.

The Borkan-1 is a is a tactical ballistic missile developed on Soviet R-17 Elbrus tactical ballistic missile bases. The missile has a range of 800 kilometers and is a new generation of Yemen’s domestically-made missiles.

Yemen’s SABA News agency quoted a Houthi spokesperson announcing the attack as a “successful test-fire on a precision long-distance ballistic missile.”

Saudi media outlets, however, reported that the kingdom’s missile systems intercepted and destroyed the solid propellant and Scud-type missile before it could cause any damage.
