KYIV, Ukraine—A Ukrainian strike killed dozens of newly mobilized soldiers in Russian-held territory in the east of the country in the single-deadliest known strike in months, piling pressure on Moscow’s military leadership, while Ukraine said it shot down at least 39 drones during another wave of attacks on Kyiv.
Russia’s Defense Ministry said Monday that Ukrainian forces used a U.S.-supplied Himars rocket system to destroy a facility used as a base for mobilized troops in the city of Makiivka, in the Donbas area of eastern Ukraine. In a statement carried by Russian state news agencies, the ministry said 63 troops had died in the blast after four Himars rockets carrying high-explosive warheads struck the facility.
