A blast rocked the Druzhba pipeline in the Russian-backed separatist city of Lugansk, Russian state news agency said.
An international oil or gas pipeline running through a key rebel-held city in eastern Ukraine blew up on Friday, Russian media said, with images showing a fireball lighting up the night sky.
The blast rocked the Druzhba pipeline in the Russian-backed separatist city of Lugansk, Russia’s RIA Novosti state news agency said.
The cause of the explosion remains unclear, occurred during a sharp escalation in fighting that has redoubled fears that Russia is preparing to invade Ukraine.
The Druzhba pipeline runs from Russia to various points in eastern and central Europe which is significant to both counterparties.
Images on social media showed a bright orange fireball lighting up the night sky.
Russian state media reported a second blast in Lugansk less than an hour after the one that appeared to hit the pipeline.
Its causes were not immediately clear, but a social media account associated with the Lugansk separatists said the second blast hit a petrol station on the city’s outskirts.
There were no immediate reports of casualties from either blast.
The region around the city of Lugansk has witnessed some of its heaviest fightings since the start of the year in the past two days.
