WARSAW, Poland — Poland's prime minister says the ongoing natural gas dispute between Russia and Ukraine is pushing his government to speed up plans to build nuclear power plants.

Donald Tusk said his Cabinet decided Tuesday to step up construction of its first-ever nuclear power plants, and that he expects them to produce power by 2020.

Tusk added that Poland will further seek to reduce its dependence on Russian gas imports, including through construction of a liquid gas storage system and a gas port.

Poland was one of several nations to see a drop in natural gas deliveries as part of the dispute between Moscow and Kiev. Warsaw was largely able to make up the shortfall through an increased inflow from pipelines running through Belarus.
