Vienna - Russia cut its supply of natural gas to Austria by 90 per cent Monday night, Austrian oil and gas supplier OMV AG said Tuesday.

The reduction came amid Ukraine's conflict with Russian state gas company Gazprom, which pipes its gas to Western Europe through the Ukraine.

OMV would be able to keep up its delivery to end customers by using its stock of 1.7 billion cubic metres, the company said.

"That way, the supply situation is secured," said Werner Auli, one of OMV's chief executives.

However, the amount of natural gas piped from Austria to Hungary fell on Tuesday, illustrating the effects of the spat between the Ukraine and Russia.

Istanbul - Russian gas supplies to Turkey via Ukrainian pipelines have been cut amid the ongoing dispute over gas between Kiev and Moscow, the Turkish government said Tuesday.

Budapest - The amount of natural gas piped into western Hungary from Austria fell on Tuesday as a result of Russia cutting supplies to Ukraine in an ongoing dispute over pricing, said Hungary's gas distributor in a statement.

The situation illustrates how the spat between Ukraine and the Russian state gas company Gazprom is having a knock-on effect in countries several links down the supply chain.

Hungary is still receiving the bulk of its natural gas via Ukraine, although Ukraine cut the daily delivery from 38 to 30 million cubic metres on Monday.

Prague  - The Czech Republic's natural gas deliveries dropped for the second day Monday as a gas row between Russia and Ukraine continued, a gas importer said.

Martin Chalupsky, a spokesman for the country's leading gas importer, RWE Transgas, said the firm on Monday received 9.5 per cent less gas than ordered for the day.

He said that the drop amounted to 1.7 million cubic metres of gas, or 2 per cent of country's daily consumption. He said the reduction would have no impact on Czech consumers.

Moscow - Russia on Monday said it will further cut gas to Ukraine by 65 million cubic metres per day, the amount Moscow says Kiev is stealing from European clients further downstream.

Gazprom cheif executive Alexei Miller proposed the measure while briefing Prime Minsiter Vladimir Putin on the standoff since the company shut off supplies to Ukraine on Janurary 1 over non-payments and a pricing dispute.

"Good, I agree. Let's begin the cuts from today," Putin was reported to have responded.
