Ministers have instructed an urgent survey of Britain's underwater power and internet cable networks amid fears that Russia could be ramping up its "seabed warfare", say reports.
Defence Secretary Ben Wallace sent British warships into the North Sea this week to ward of Russian attacks following a series of explosions of gas pipelines in the Baltic. Ministers are now seeking to check on the UK's key pipelines and cables to ensure that they are clear of remote mines.
Authorities in Denmark are still looking into a series of blasts which damaged the critical Nord Stream 1 and 2 gas pipelines last month.
