Moscow (AFP) - Russia on Thursday accused Washington of not meeting its obligations under the Syria ceasefire agreement struck with Moscow, while criticising US officials for voicing scepticism over cooperation between the two countries.

Military spokesman Igor Konashenkov in a statement slammed Washington for what he called "rhetorical fog" intended "to hide the fact that it is not fulfilling its part of the obligations."
