On Sept. 2, Russia's embassy in Germany said Germany's accusation that Moscow was responsible for the attempted attack at Leipzig airport was "unfounded." Germany on Sept. 1 had held Russia responsible, summoned Russian ambassador Nechayev, registered a protest and announced sanctions. The embassy described the incident as a "provocation." Ambassador Nechayev said the German measures mark an "unprecedented deterioration" in bilateral ties and that Germany will bear any resulting consequences.
