Russian forces launched what authorities reported was an unprecedented number of missiles at Kyiv, Lviv, and other major cities in Ukraine on Thursday morning, escalating their fight against the nation as their ground struggle continues in the east.

In a “massive attack.” The Ukrainian military declared that 81 missiles were launched,  including six Kinzhal ballistic missiles capable of bypassing air defense systems in Kyiv.

Yurii Ihnat, spokesman for the Air Force Command of Ukraine, said on Ukrainian television Thursday:

“The attack is really large-scale and for the first time using such different types of missiles. We see that this time as many as six Kinzhal were used. This is an attack like I don’t remember seeing before.”
