"A drone strike caused a massive power outage in Luhansk and other municipalities of the republic", - the press service of the "LNR government" said in a statement.
The statement mentions only one Ukrainian drone. It does not specify where or which facility was struck, causing such large-scale consequences for the energy sector in occupied Luhansk oblast.
"The risk of further enemy strikes on energy infrastructure remains, which could significantly complicate restoration work", - the "government" indicated, suggesting that repairing the damage could take a long time.
