Ukraine has resumed gas imports via the southern Transbalkan route following a sharp increase in Russian attacks on the country’s gas and energy infrastructure, data from the Ukrainian transit operator showed on Wednesday.

Axar.az informs, citing Reuters, Russia intensified strikes on Ukraine’s gas sector in October, depriving Kyiv of at least a half of its own gas production, forcing it to import an additional 4 billion cubic meters of gas to compensate for the decline.

The data showed that Ukraine will receive 1.1 million cubic meters (mcm) of gas from the Transbalkan route on Wednesday, after the import of 0.78 mcm on Tuesday.

The route links Ukraine to LNG terminals in Greece, via Moldova, Romania and Bulgaria.
