British and Norwegian patrols located them with buoys that detect sound.

There is no evidence any damage was done to U.K. cables and pipelines.

The operation was part of a broader effort to counter Russia's shadow fleet.

Political Context

Healey said Putin would want us to be distracted by the Middle East, but Russia is the primary threat.

The operation came amid escalating tensions over Russia's use of the English Channel to move sanctioned oil tankers.

Downing Street announced that British armed forces could now intercept and seize ships belonging to Russia's phantom fleet.

Healey said, We are ready to act.
