MINSK, Nov 27 (Reuters) - Russia and United States will ink a new nuclear weapons reduction pact this year but may not manage to sign the treaty by a Dec 5 deadline, a Kremlin source told Reuters on Friday.

The agreement will be signed “in a European country” in December, the source said. “We may not be able to do it by Dec. 5,” the source said.
