COPENHAGEN, Denmark (AP) — Russian President Vladimir Putin on Friday accused the West of sabotaging Russia-built natural gas pipelines under the Baltic Sea to Germany, a charge vehemently denied by the United States and its allies. Nordic nations said the undersea blasts that damaged the pipelines this week and have led to huge methane leaks involved several hundred pounds of explosives. The U.S.-Russia clashes continued later at an emergency meeting of the U.N. Security Council in New York called by Russia on the attacks on the Nord Stream 1 and 2 pipelines, and as Norwegian researchers published a map projecting that a huge plume of methane from the damaged pipelines will travel over large swaths of the Nordic region.
