"A completely unconstructive position, an unconstructive approach," RIA Novosti quoted him as saying.

According to Ushakov, there will not be enough objectivity in this investigation, since Denmark does not want to allow the Russian side to the investigation.

He said that he twice summoned the chargé d'affaires of Denmark, suggesting that the authorities consider the possibility of conducting a joint investigation with the participation of specialists of the Ministry of Emergency Situations, and "in case of detection of some dangerous element, to conduct mine clearance" on the pipeline, however, the answer "was rather vague."

Earlier, Danish Foreign Minister Lars Løkke Rasmussen said that Copenhagen would not allow Moscow to participate in the investigation of sabotage on Nord Streams.
