At least seven people have been killed and 11 others wounded in a Ukrainian drone strike on a passenger bus in Russia’s Donetsk People’s Republic (DPR), local governor Denis Pushilin has said.

The bus, which was traveling between Moscow and the Crimean city of Simferopol, was attacked in the town of Enakievo in the western part of the DPR, Pushilin wrote in a post on Telegram on Wednesday morning.

“The Ukrainian fascists have committed another act of unprecedented, inhumane aggression,” the governor said.

Russia’s Investigative Committee has announced that a terrorism case has been opened over the attack on the bus.

Russia was hit by another major Ukrainian drone attack overnight, with 345 UAVs shot down across the country, according to the Defense Ministry. The interceptions took place over Moscow, Leningrad, Belgorod, Bryansk, Voronezh, Kaluga, Kursk, Novgorod, Orel, Pskov, Rostov, Smolensk, Tver, Tula, and Krasnodar regions, as well as over Crimea and the Sea of Azov, the ministry said.

Several people were hurt and infrastructure damaged in Ukrainian drone attacks on St. Petersburg on the opening day of the 29th St. Petersburg International Economic Forum (SPIEF), local governor Alexander Beglov said.

At least 59 UAVs were shot down by air defenses above Leningrad Region, according to governor Aleksandr Drozdenko. Leningrad Region surrounds St. Petersburg, which has the status of a federal city.
