Saudi Patriot PAC-2 SAM battery in Riyadh fired MIM-104C Surface to Air Missiles at a Burkan 2-H SRBM (Short Range Ballistic Missile) in the night between Mar 25 and 26, 2018.

The SRBM was reportedly intercepted by one of the SAMs (at least 7 according to journalist Babak Taghvaee were launched) but at least two of them failed: one hit a resindential area (at the time of writing the number of casualties/fatalities is unknown), whereas another one exploded mid-air shortly after launch.
