Ukraine 'Ultimatum' Deadline Passes, US Reduces Economic And Military Ties With Russia

A reported deadline laid down by Russian forces to Ukrainian troops in the Crimea has passed at 5 a.m. local time Tuesday (10 p.m. EST) without reports of incidents. The Russian news agency Interfax reported earlier Monday that a Black Sea Fleet commander said the fleet had given Ukrainian military forces in Crimea until "dawn on Tuesday" to surrender their arms or face "a real assault."
