Ukraine’s energy minister says the country’s power infrastructure is, once again, under widespread attack.

So far, explosions have been reported from one end of the country to the other, in a series of missile and drone attacks that began late last night.

Reports are still coming in from Kharkiv in the east to Lutsk in the far west and Odesa in the south.

Emergency power cuts have already been introduced – a standard procedure when the authorities see that the country’s entire grid is being targeted.

Ukrainian officials have been warning for some time that Russia has been stockpiling cruise and ballistic missiles in order to mount coordinated attacks on power infrastructure throughout the winter.

This appears to be the second such attack this month.

Ukraine’s parliamentary commissioner for human rights, Dmytro Lubinets, says Russia’s actions made no military sense.

The attacks, he said, were aimed at intimidating the civilian population and creating a humanitarian crisis.
