Roughly three-quarters of Crimea's population is reported to be still without electricity after four power transmission towers were blown up in Ukraine's Kherson region just north of the peninsula.

The state of emergency remains in place Monday. 

Currently three major cities, Simferopol, Yalta, and Saky, are provided electricity by gas-powered generators, whereas Sevastopol, Crimea's most populated city, is powered by Russian Navy installations. 

Although Crimea was annexed by Moscow in March 2014 in a move that has led to international sanctions against Russia, Ukrainian authorities have continued to supply power to the peninsula.

Those supplies are delivered to Crimea along four main power lines from Ukraine's Kherson region.

But transmission towers along all four of those power lines were blown up on November 20 and 21, and groups of Crimean Tatar activists from the peninsula's civil blockade reportedly have been preventing engineers from reaching the sites to carry out repairs.
