Monday's explosion in a Ukrainian gas pipeline has not affects natural gas deliveries to Poland from Russia via Ukraine, Polish Economy Minister Piotr Wozniak said Tuesday.

"The flow of gas is normal. Other gas receivers of the European Union have not signaled any abnormalities. Apparently the situation is under control," Polish PAP news agency quoted Wozniak as saying.

The explosion Monday destroyed a 30-metre section of a trunk gas pipeline carrying Russian gas across Ukraine to Europe.
