Sweden has rejected plans for a joint investigation with Denmark and Germany into recent incidents at the Nord Stream 1 and Nord Stream 2 gas pipelines, the German weekly Spiegel reported, citing German security sources.

Sweden has decided that it cannot share the results of its investigation with other states for security reasons.

Germany's Federal Police have completed their part of the investigation into an alleged act of sabotage at the Nord Stream pipeline and handed over their findings, an interior ministry spokesman said.
