WASHINGTON, March 30 - U.S. Secretary of State Antony Blinken said in an interview broadcast on Sunday that it was ultimately up to those building the Nord Stream 2 natural gas pipeline whether to complete it despite opposition from Washington, Reuters reported.

Blinken said he had told his German counterpart that U.S. sanctions against the pipeline from Russia to Germany were a real possibility and there was "no ambiguity" in American opposition to its construction.
