"Now I will not give an answer to this question to you. I believe that we will consider this issue soon," Novak told reporters on Monday when asked whether Russia was mulling counter-measures against Ukraine, for instance, in the form of limitations on coal shipments.

As UNIAN reported earlier, the two out of the four transmission pylons on the administrative border between mainland Ukraine and Russian-occupied Crimea, which were damaged by blasts in the early hours of November 20, were destroyed completely in a new explosion on November 21.

The four transmission pylons belong to the power grids supplying electricity to Crimea and some areas in Ukraine's Kherson and Mykolaiv regions.

After the incident, the Crimean occupying authorities reported about a total power blackout on the peninsula in the early hours of November 22. According to some reports, strategic facilities were switched to the independent power supply.
