More than 51,000 households were left without gas and 1,500 apartment buildings had no winter heat in Moldova's pro-Russian separatist enclave, authorities said on Monday, as Moldova and Russia traded blame for an escalating energy crisis.

"Russian propaganda tries to create a story in which Moldova becomes a ‘problematic actor,’ although the government has proposed clear solutions to avoid the crisis," Moldovan government spokesperson Daniel Voda said on Jan.

The head of Moldova’s breakaway region Transnistria has urged residents to burn firewood for heating and warned that blackouts cannot be avoided, after Moscow stopped supplying gas via Ukraine.
