WARSAW, Poland (AP) Polish and Bulgarian leaders accused Moscow of using natural gas to blackmail their countries after Russias state-controlled energy company said it would stop supplying the two European nations Wednesday.

The gas cutoff came after Russian President Vladimir Putin said last month that unfriendly countries would need to start paying for gas in rubles, Russias currency, which Bulgaria and Poland refused to do.

Russian energy giant Gazprom said in a statement that it hadnt received any payments from Poland and Bulgaria since April 1 and was suspending their deliveries starting Wednesday.

If the countries siphon off gas intended for other European customers, deliveries to Europe will be reduced by that amount, the company said.

Polish Prime Minister Mateusz Morawiecki told Polands parliament that he thinks the suspension was revenge for new sanctions against Russia that Warsaw imposed over the war in Ukraine.

Morawiecki vowed that Poland would not be cowed by the cutoff. He said the country was safe from an energy crisis thanks to years of efforts to secure gas from other countries.

Lawmakers stood and applauded when he said that Russias gas blackmail would have no effect on Poland.

The new sanctions, announced Tuesday, targeted 50 Russian oligarchs and companies, including Gazprom. Hours later, Poland said it had received notice that Gazprom was cutting off its gas supplies for failing to adhere to the demand to pay in Russian rubles.
