Explosions are reported in several cities across the country, including Kyiv
Early on Thursday, the Ukrainian air force issued a nationwide air raid warning “due to the threat of missile danger”
The warnings were issued for Kyiv, Rivne, Vinnytsia, Kropyvnytskyi, Balta, Mykolaiv and other regions in Ukraine.
The mayor of Kharkiv, Igor Terekhov, also reported strikes in the city, as did officials from Sumy and Volyn.
The war in Ukraine escalated last week when Russia used a new Oreshnik intermediate-range ballistic missile to strike Ukraine.
Vladimir Putin authorised the use of the missile after Ukraine fired British and American missiles at targets in Russian territory for the first time.
As a result of the UK’s support for Ukraine, Russia has also threatened to attack the UK.
