LONDON, Oct 5 (Reuters) - The Kremlin said on Wednesday that Russia must be part of investigations into last week's explosions in the two Nord Stream gas pipelines under the Baltic Sea."So far, from those news conferences which took place in Denmark and Sweden, we've heard disturbing statements that any cooperation with the Russian side is ruled out," Kremlin spokesman Dmitry Peskov said.Register now for FREE unlimited access to Reuters.comEuropean governments and NATO say the two Nord Stream pipelines were attacked in an act of sabotage, which has further roiled global energy markets after months of tension and disrupted supplies since Russia's invasion of Ukraine.The operators of the two pipelines between Russia and Germany have said they are currently unable to inspect the damaged sections because of restrictions imposed by Danish and Swedish authorities, in whose waters the blasts and leaks occurred.Nord Stream 2 AG, Switzerland-based operator of the second pipeline, said on Tuesday it will examine the condition of the leaking pipelines once a police investigation of the "crime scene" is completed and a cordon is lifted."
