COPENHAGEN, Denmark (AP) — Russian President Vladimir Putin on Friday accused the West of sabotaging Russia-built 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 led to huge methane leaks involved several hundred pounds of explosives.

The claim by Putin came ahead of an emergency meeting Friday at the U.N. Security Council in New York 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 released by damaged pipelines will travel over large swaths of the Nordic region.

Speaking Friday in Moscow at a ceremony to annex four regions of Ukraine into Russia, Putin claimed that the “Anglo-Saxons” in the West have turned from sanctions on Russia to “terror attacks,” sabotaging the Nord Stream 1 and 2 pipelines in what he described as an attempt to “destroy the European energy infrastructure.” 

He added that “those who profit from it have done it,” without naming a specific country.

Moscow says it wants a thorough international probe to assess the damage to the pipelines, which carry Russian natural gas to Europe. Putin’s spokesman has said “it looks like a terror attack, probably conducted on a state level.”
