Sweden opens inquiry into damaged undersea cable as Nato deploys ships

A vessel has been seized after suspected sabotage of fibre optic line, probably due to external influence, Latvia says

An undersea fibre optic cable between Latvia and Sweden was damaged on Sunday, probably as a result of external influence, Riga has said, prompting Nato to deploy patrol ships to the area and triggering a sabotage investigation by Swedish authorities.

Sweden's security service has seized control of a vessel as part of the inquiry, the country's prosecution authority said.
