Transdniestria's separatist leader, Vadim Krasnoselsky, said his region had told Moldova's pro-European authorities two days earlier that it was ready to agree to a deal to accept - and pay for - gas supplies provided by the Moldovagaz national company.

Transdniestria's pro-Russian leaders said via the region's official Telegram channel that daily rolling blackouts would be reduced to three hours on Sunday from eight hours earlier this week, though on Sunday they said the cut-off time will be extended to five hours from Monday.

Tens of thousands of people in Transdniestria have been without gas or winter heating since Jan. 1 when Russia's Gazprom suspended gas exports to the region, citing an unpaid Moldovan debt of $709 million that Chisinau does not recognise as valid.
