Russian military strength along the border with Ukraine was on full display, Friday.
Soldiers sat and waited... while Ukrainian border guards crossed the frontier to inspect the huge Russian aid convoy that has caused Kiev so much alarm.
Kiev has insisted on inspecting the trucks before they move across the border toward eastern Ukraine.
Authorities say they suspect the aid convoy is a cover for Russian military intervention... Something Moscow denies.
The head of the Red Cross mission in Ukraine says each truck is staffed by a driver and at least one passenger. Ukraine authorities say only one driver - accompanied by a Red Cross delegate - will be allowed to cross.
Some 280 trucks are now waiting to enter Ukraine to deliver aid to beseiged pro-Russian rebels
But with more than 40,000 Russian troops massed near the border, Kiev and NATO fear a Russian invasion, and are anxiously waiting for Moscow's next move.
