KYIV, Ukraine— Russian drones struck the southern Ukrainian port city of Odesa overnight, killing two people and injuring at least 17, Ukrainian authorities said Saturday. Meanwhile, three attack helicopters and an anti-aircraft missile system were destroyed in the Russian-occupied Crimean Peninsula.

Ukraine’s Security Service agency deployed special drones to attack the Kirovske military airfield, a Ukrainian security official said Saturday.

“Available data indicate the destruction of multipurpose and attack helicopters Mi-8, Mi-26 and Mi-28, as well as the self-propelled, anti-aircraft missile and gun complex Pantsir-S1,” according to the official, who spoke about the operation on condition of anonymity.

In Odesa, a drone slammed into a residential tower block in the city, causing damage to three floors and trapping residents, emergency services said. The two killed in the attack were a married couple, according to regional Gov. Oleh Kiper.
