Britain would be 'extremely concerned' if Spain refuels Russian warships

BRUSSELS (Reuters) - Britain would be "extremely concerned" if Spain refuels a Russian carrier battle group heading through the Mediterranean towards Syria, British Defence Secretary Michael Fallon said on Wednesday. "We'd be extremely concerned that any NATO member should consider assisting a Russian carrier group that might end up bombing Syrian civilians," Fallon told reporters. "On the contrary, NATO should be standing together." (Reporting by Robin Emmott; Editing by Alastair Macdonald)
