MOSCOW, May 21, 2026 (BSS/AFP) - A Ukrainian drone strike killed two people in Russia's southwestern Samara region on Thursday, the governor said, as both sides continue to trade attacks with no end to the war in sight.

"The Ukrainian armed forces are attacking the city of Syzran with drones," wrote Vyacheslav Fedorishchev on Telegram, giving the toll of two dead.

People were also wounded in the attack on Syzran, which is home to a major oil refinery, according to Fedorishchev.

Claiming fair retaliation for the Russian army's near-daily bombardments of Ukrainian cities across the four-year conflict, Ukraine has regularly launched attacks inside Russia, including on areas thousands of miles away from its territory.

Kyiv insists it targets Russian military sites, as well as energy installations in a bid to disrupt the fossil fuel revenues Moscow uses to fund the offensive.

Diplomatic efforts led by Washington to end the conflict have been deadlocked, especially with the United States' attention diverted to the war against Iran since late February.
