Ukrainian Prime Minister Arseniy Yatseniuk has said that the Ukrainian gas network operator Ukrtransgaz has completed ahead of the schedule the repairs of the pipeline damaged by militants in Donetsk region, and the supply of gas to Mariupol and Berdiansk has resumed.

"Thanks to the incredible efforts of the Ukrainian gas industry workers, both breaches were patched up in record time. The repaired pipelines have been connected to the network, and they are being filled with gas," the premier wrote on his Facebook page on Sunday evening.
