Tension Is High at Russia-Ukraine Border

From BBC News:

Ukrainian officials quoted by the Interfax agency said the cargo, bound for cities in eastern Ukraine held by pro-Russian rebels, was being checked.

Ukraine fears the convoy may carry military supplies for the rebels, an accusation Russia has rejected.

On Thursday, two reporters said they saw Russian army vehicles heading into Ukraine, into rebel-held territory.

Ukrainian security officials said that they had spotted a column of armoured personnel carriers and military lorries crossing into Ukraine.

So, Russia is denying what independent journalists have themselves seen.
