KYIV, Ukraine (AP) — Russia conducted an array of aerial attacks on Ukraine with cruise missiles, drones and ballistic missiles, Ukraine's air force said Thursday, while the chief of the army said Russia is increasing its troop concentration in the Kharkiv region where Moscow's forces have made significant advances in a spring offensive.

Russian forces are increasing the number of troops near the settlements of Strilecha - Lyptsi and Vovchansk in Kharkiv Oblast, but these forces are not enough for a full-scale offensive. Source: Oleksandr Syrskyi,
