Explosions were reported in three Ukrainian cities early Saturday, including the capital Kyiv where a fire broke out at a critical infrastructure facility.
Blasts were also heard in Zaporizhzhia in the southeast and Kharkiv in the northeast, officials said.
“The enemy is attacking Zaporizhzhia again. No detailed information yet on explosions or casualties,” Zaporizhzhia city council secretary Anatolii Kurtev wrote on Telegram.
In Ukraine’s northeast, the head of Kharkiv’s military administration urged residents to take shelter.
“Attention, residents of Kharkiv city and region. Remain sheltered. The occupiers are striking again!” Oleh Synehubov wrote on Telegram.
Kharkiv mayor Ihor Terekhov said Russia had fired four S-300 missiles, with two hitting the city.
The head of Kyiv region military administration, Oleksiy Kuleba, said explosions were heard around 6 a.m. local time on Saturday.
“A fire broke out at a critical infrastructure facility. Response teams are on site. As of now, no casualties have been reported,” Kuleba wrote.
However, Oleksandr Pavliuk, a Kyiv-based commander in the Ukrainian army, said the explosions in Kyiv were not caused by Russian attacks.
“The explosions are not connected with the threat from the air or air defense, as well as with any military actions,” Pavliuk wrote on Telegram.
“If there was a threat – you would have heard the alarm. The cause of the explosions will be reported separately.”
