"It is sometimes said that the while Russia may not be officially supporting the rebels, it is surely providing them with indirect support by allowing volunteers and weapons to cross the border. Even this version of official Russian complicity, however, has been challenged by some Western reporters on the scene, most notably, Mark Franchetti who wrote a remarkable piece for the London Sunday Times after spending several weeks embedded with rebel forces. His assessment is backed by the UN High Commissioner for Human Rights and the OSCE observer mission that has been deployed to the border region since the end of July. Both say they have seen no evidence of weapons or military personnel crossing from Russia into Ukraine during this time, even as U.S. and NATO officials say the exact opposite." (thanks Regan)
