Ukrainian President Volodymyr Zelenskyy confirmed on Saturday that his country struck the Progress Rocket Space Center deep within Russia using ground-launched cruise missiles.

“In Russia’s Samara region, one of the key enterprises within Roscosmos—the Progress Center, which was involved, among other things, in electronics production–was hit,” Zelenskyy said on the social media site X. “Flamingo missiles were used. A good achievement.”
