- Summary- Companies- Russia says UK navy personnel blew up pipelines- Russia says UK navy personnel helped attack Crimea- Russia does not give evidence for claim- Britain denies Russian claims- Russia says will seek UN attentionLONDON, Oct 29 (Reuters) - Russia's defence ministry said on Saturday that British navy personnel blew up the Nord Stream gas pipelines last month, a claim that London said was false and designed to distract from Russian military failures in Ukraine.Maria Zakharova, a spokeswoman for Russian foreign ministry, said Moscow will seek reaction from the U.N. Security Council saying on social media Moscow wanted to draw attention to "a series of terrorist attacks committed against the Russian Federation in the Black and Baltic Seas, including the involvement of Britain in them".PIPELINE MYSTERYSweden and Denmark have both concluded that four leaks on Nord Stream 1 and 2 were caused by explosions, but have not said who might be responsible.The Kremlin has repeatedly said allegations of Russian responsibility for the damage were "stupid" and Russian officials have said Washington had a motive as it wants to sell more liquefied natural gas (LNG) to Europe.BLACK SEA FLEETRussia said meanwhile that Ukrainian forces attacked ships from the Black Sea Fleet in Sevastopol, the biggest city in Russian-annexed Crimea, in the early hours of Saturday."
