MOSCOW – Russia and Turkey vowed on Dec. 20 not to let the assassination of a top Russian diplomat by an off-duty Turkish police officer derail their work or their fight against terrorism. Along with Iran, they pledged to expand a fragile cease-fire deal involving Syria’s government and the opposition.
A team of 18 Russian investigators landed in Ankara to look into the killing of the envoy, Ambassador Andrey G. Karlov, whose body was to be returned to Russia on the same plane in which the investigators arrived.
