Russia fired a rarely-used missile during its aerial assault on Thursday

Russia’s overnight missile attack on Thursday showered Ukraine with an array of missiles, in one of Moscow’s biggest aerial assaults for months.

Russia launched a total of 95 missiles of various types over the past day, 34 of which were intercepted, the General Staff of the Armed Forces of Ukraine said in a morning update on Friday, as well as a number of Iranian-made Shahed drones.

That array included cruise missiles that were launched from both the sea and the air; six different kinds were used in the early hours of Thursday morning, according to Valerii Zaluzhnyi, commander in chief of the Ukrainian Armed Forces.

Much attention has been focused on the six launches of Kinzhal air-launched ballistic missiles, which are especially difficult to stop.

The powerful weapon has rarely been seen over the country’s skies. Its first known use in Ukraine was last March and occasionally used since, according to the Center for Strategic and International Studies (CSIS).
