Ukraine and Russia will attempt fresh talks this morning, ahead of a Russian deadline for Kiev to pay a $1.95 billion (£1.15 billion) debt or have its gas supplies cut off.
The two countries failed to end a gas pricing dispute at talks yesterday.
Russia's decision to stop deliveries to Kiev could disrupt the gas flow to the European Union, which receives its energy via Ukraine.
