Crimea has been left without power after pylons carrying power lines which supply electricity from Ukraine were reportedly blown up on November 21.

According to local reports, all four power lines were cut, leaving the region’s two million inhabitants without electricity.

Images circulated on social media appeared to show Ukrainian flags attached to the damaged pylons.

Crimea was annexed by Russia in 2014, but the Ukrainian authorities have continued to supply power to the area.

Crimean authorities said they had managed to partially reconnect the cities of Simferopol, Yalta and Saky using generators.

Crimea’s Deputy Prime Minister Mikhail Sheremet said the peninsula’s hospitals had backup power sources and would not be affected.

The Crimean Emergencies Ministry has declared a state of emergency and put rescue teams on high alert.

“Crimea is completely cut off,” Viktor Plakida, the director of Crimea Energy, told Russia’s Tass news agency.

A local emergency response official told Russia’s Tass news agency that Crimea was “operating in standalone mode”.

Crimea can only produce half the power it needs, Mikhail Sheremet said.

Two of the four main power lines were cut in an earlier attack on November 20, reports said.

Ukrainian authorities said they encountered activists blockading the site when they tried to repair the damaged pylons.

“The nature of the damage shows that it took place as a result of shelling or the use of explosive devices,” Ukraine’s state energy company Ukrenergo said in a statement.

Crimean Tatars, an ethnic group native to the peninsula who oppose Russian rule, held a protest at the site of the broken power lines in Kherson region, Russia’s RIA news agency reported.
