Russian defense minister orders doubling of high-precision weapons production

German magazine Der Spiegel has identified the boat that was searched by authorities in connection with the explosions that knocked out the Nordstream gas pipeline in September.

The sailing vessel “Andromeda” was searched in January, according to Der Spiegel. The German general prosecutors’ office said last week that it had searched an unnamed boat that month.

Der Spiegel says that the “Andromeda” was the vessel in which an unidentified six-man crew allegedly sailed to the explosion area in the Baltic Sea.

According to the marine websites vesselfinder.com and marinetraffic.com, the “Andromeda” is German-flagged and measures 13 meters (42.6 feet) in length and 4 meters (13.1 feet) wide.

CNN contacted the company that rents out the “Andromeda,” but got no comment.

Last Friday, a German government spokesman was asked about the “Andromeda,” but referred any questions to the German general prosecutors’ office.

The investigation into the explosions, which targeted pipelines delivering Russian gas to Europe, has also reached Denmark.

Søren Thiim Andersen, a local official on the island of Christiansø, told CNN that investigators had searched his harbor mooring online booking system.

They also asked him to post an appeal for photos of boats that had visited the island from 16-18 September last year on a local Facebook page.

“We were contacted by Danish police in December about boats coming to the harbour, if we had any information locally here on Christiansø, about which boats that have been here in the harbour,” he said.

“I don’t know if the police found what they were looking for on the island,” he said.

Christiansø is 20 kilometers (12 miles) northeast of the Danish island of Bornholm, near where the explosions happened.

Some context: Mystery has surrounded who might be responsible for the brazen sabotage last September, which damaged two pipes transporting Russian gas into the European Union and targeted a crucial source of revenue for Moscow. Both pipelines were closed at the time of the attack.

A report by the New York Times cited new intelligence that a “pro-Ukrainian group” may have been behind the attack. Ukraine has denied any involvement.
