Germany’s defense minister says officials have to assume that damage to two data cables under the Baltic Sea, one of which ends in Germany, was caused by sabotage — though he says they have no proof at present.

Germany and Finland say they are "deeply concerned" after an undersea cable linking the countries was severed.The rupture of the 1,170km (730-mile) telecommunications cable - which is being investigated - comes at a time of heightened tension with Russia.
