Russian expels 4 British diplomats

MOSCOW - Russia said Thursday it will expel four British diplomats and suspend counterterrorism cooperation with London, the latest move in a mounting confrontation over the radiation poisoning death of former KGB officer Alexander Litvinenko.

Britain had announced Monday the expulsion of four Russian diplomats and restrictions on visas issued to Russian government officials after Moscow refused to extradite Andrei Lugovoi, accused of killing Litvinenko in London last November.
