U.S. Secretary of State Mike Pompeo warns that sanctions could be imposed on the Nord Stream 2 gas pipeline project between Germany and Russia. The project will be covered by the previously enforced Sanctions Act.

- We expect sanctions to be considered for participants in this project, Pompeo said.

The United States has opposed the construction of the pipeline because it sees it as increasing Russia's economic and political influence in Europe too much.

Previous U.S. sanctions halted construction work on the pipeline in Danish waters in December. However, Denmark recently accepted an exemption allowing construction to continue.

Germany has condemned US sanctions and sees them as interference in its internal affairs.
