OSCE 'very concerned' by tanks, convoys in Ukraine

The OSCE said it is "very concerned" after its monitors witnessed columns of tanks, howitzers and troop carriers moving through east Ukraine in territory held by pro-Russia separatists.

Monitors from the European security organization said in a statement late yesterday they had "observed convoys of heavy weapons and tanks" in the rebel-held city of Donetsk and nearby Makiivka.
