European Union suspects 'sabotage' in Nord Stream pipeline explosion | USA TODAY

A series of explosions caused leaks on two gas pipelines that feed natural gas from Russia to Germany.

Two underwater explosions, or shakings, were recorded in the Baltic Sea shortly before leaks were found in the Nord Stream 1 and 2 pipelines, which were pressurized with natural gas. Both pipelines were not operational.

The first shaking, measuring 2.3 on the Richter scale, was recorded southeast of Bornholm, a Danish island, the Guardian reported, citing Denmark's Geological Survey. The second, with a magnitude 2.1 earthquake, was reported northeast of the island.
