Blasts Hit Russian-Held Territory as Ukraine Intensifies Attacks Beyond Enemy Lines.

An ammunition depot in Russia’s southern Belgorod region bordering Ukraine ignited late Thursday, the region’s governor wrote on his social-media pages. Around the same time, unverified videos on social media showed billowing clouds of smoke and fire in the city of Kadiivka in Ukraine’s eastern Luhansk region, which Russian forces captured in early July. Russian-installed authorities in Luhansk said Ukrainian forces had struck the city with U.S.-supplied Himars mobile rocket launchers.
