KYIV, Ukraine — Russia launched 188 drones against most regions of Ukraine in a nighttime blitz, the Ukrainian air force said Tuesday, describing it as a record number of drones deployed in a single attack.

Most of the drones were intercepted, according to the air force, but apartment buildings and critical infrastructure such as the national power grid were damaged. No casualties were immediately reported in the 17 targeted regions.

The Russian Defense Ministry, meanwhile, issued a rare official acknowledgment of its assets recently being hit on its own soil by U.S.-made ATACMS missiles, after President Joe Biden authorized Ukraine to use the longer-range weapons.

Russia has been hammering civilian areas of Ukraine with increasingly heavy drone, missile and glide bomb attacks since the middle of the year.

At the same time, Russia’s army has largely held the battlefield initiative for the past year and has been pushing hard in the eastern Donetsk region where it is making significant tactical advances, according to Western military analysts.
