Britain, U.S. sending planes, troops to deter Russia in the east

By Robin Emmott and Phil Stewart BRUSSELS (Reuters) - Britain said on Wednesday it will send fighter jets to Romania next year and the United States promised troops, tanks and artillery to Poland in NATO's biggest military build-up on Russia's borders since the Cold War. Germany, Canada and other NATO allies also pledged forces at a defense ministers meeting in Brussels on the same day two Russian warships armed with cruise missiles entered the Baltic Sea between Sweden and Denmark, underscoring East-West tensions. In Madrid, the foreign ministry said Russia had withdrawn a request to refuel three warships in Spain's North African enclave of Ceuta after NATO allies said they could be used to target civilians in Syria.
