The mystery still hangs over the major gas leaks that appeared on September 26 on the two Nord Stream gas pipelines, designed to transport Russian gas to Germany through the Baltic Sea.
The Swedish investigation had concluded in November to sabotage: "the
analyzes which have been carried out show remnants of explosives on several of the foreign objects discovered
", declared Mats Ljungqvist, the prosecutor in charge of the investigation in Sweden.
Explosions had been recorded before the leaks began.
But while another investigation is underway in Germany, this has so far failed to identify evidence of responsibility for the Russians, who were suspected in the Western press immediately after the incident. .
Moscow's involvement "
cannot be proven at this time
" as "
the investigation continues
", Prosecutor General Peter Frank
told German newspaper
Die Welt on Saturday.
Germany dispatched two research vessels, which took samples of water and rock from the explosion site, as well as debris from the two pipelines.
"
We are carrying out scientific expertise
" on these samples, added the magistrate.

The two investigations - the Swedish and the German - took place concurrently because the incident took place in international waters.
But the investigators of the two countries “
are in contact
”, specified Peter Frank.
At the same time, the Nord Stream consortium, of which the Russian Gazprom is the majority shareholder, had sent a civilian ship under the Russian flag to carry out an inspection in the Swedish zone.
In November, Nord Stream also received authorization to inspect the gas pipelines in the Danish area, where another investigation is underway.
