Ukraine has launched a wave of overnight drone attacks on Russia, causing fires at two Russian energy facilities.

According to Russia’s defence ministry, more than 158 Ukrainian drones targeted 15 regions of the country, including the capital Moscow.

The Russian military claimed that these drones were intercepted and destroyed.

But as a result of the attack a fire has broken out at an oil refinery in Moscow in a “separate technical room”, the city’s mayor said.

Sergei Sobyanin reported that at least 11 drones targeted the capital city and the surrounding areas.

Meanwhile, 75 miles (120km) from the Russian capital, in the Tver region, loud blasts were heard close to the Konakovo Power Station.
