Russia says concerned by talk of U.S. arms supplies to Kiev

MOSCOW (Reuters) - A Russian foreign ministry spokesman said on Thursday Moscow was deeply concerned with continued talk of the United States starting large-scale arms supplies to Ukraine.

"Russian-American ties will suffer colossal damage if the people of Donbass start getting killed with American arms," Alexander Lukashevich told a news conference, referring to the eastern Ukrainian region controlled by pro-Russian rebels.
