CNN reports somewhere in southern Russia, a convoy of 280 white-painted trucks snaked its way Tuesday toward the Ukrainian border. Depending on whom you ask, what's inside may either be a treasure trove of relief goods for war-weary civilians, or the vanguard of a Russian invasion of eastern Ukraine. With thousands of Russian troops still posted near the Ukrainian border and Ukraine's military putting increasing pressure on pro-Russian fighters around the city of Donetsk, many in Ukraine and elsewhere feared the latter. Without offering proof, Ukrainian officials have even accused Russia of repainting military vehicles white to disguise their efforts. Russia has acknowledged sending the convoy. In a conversation Monday with the President of the European Commission, Putin said his country was working with the International Committee of the Red Cross to deliver aid to civilians suffering as a result of savage fighting there. Except Red Cross spokesman Andrew Loersch said the agency doesn't have any agreement with Russia on such a convoy.
