Five trucks transporting S-300 missile systems were spotted in Russian-occupied Mariupol heading toward Ukrainian-controlled Zaporizhzhia, Petro Andriushchenko, an advisor to the mayor of Mariupol, wrote on Telegram on May 2.
S-300 are Soviet missile systems designed for air defense. However, Russia has been using the repurposed S-300 to attack targets in Ukraine.
Attacks with S-300 systems usually have repeatedly targeted populated areas in the city of Zaporizhzhia after such movements, Andriushchenko said, urging residents not to ignore air alerts.
Two Russian missiles hit a private residence in Zaporizhzhia on April 9, acting Zaporizhzhia Mayor Anatolii Kurtiev reported on Telegram.
The city has been subject to frequent attacks since the start of the full-scale invasion.
Russia declared an illegitimate annexation of Zaporizhzhia Oblast in the fall, along with Kherson, Donetsk, and Luhansk oblasts.
Only part of Zaporizhzhia Oblast is under Russian occupation.
