Kyiv officials say Russia uses 6 types of missiles in strikes on Ukraine capital

Authorities in Ukraine's capital Kyiv say Russia's military has used six types of missiles in its attacks on the city this year, including hypersonic Zircon missiles.

The authorities revealed in a social media post on Monday that Russia launched more than 180 missiles and drones against Kyiv in the first three months of the year.

The officials said the missiles included five Zircon units -- which are sea-based hypersonic missiles said to be capable of traveling at nine times the speed of sound. They called for more support from the international community, saying more air defense means more lives saved.

Russia's defense ministry on Monday said Russian troops were gaining positions, as they continued their attacks around Avdiivka in the Donetsk region in eastern Ukraine.

The Institute for the Study of War, a US think tank, said on Sunday that Russia's military may be prioritizing the Avdiivka area. It added that Russian troops may focus their operation on western Donetsk in the spring and summer of this year.

The institute also said, "Russian forces will likely only be able to launch a concerted large-scale offensive operation in one operational direction at a time due to Russia's own manpower and planning limitations."
