Putin orders troops into east Ukraine after recognising breakaway regions

Putin's announcement drew international condemnation and immediate U.S. sanctions to halt U.S. business activity in the breakaway regions and ban import of all goods from those areas

Russian President Vladimir Putin ordered the deployment of troops to two breakaway regions in eastern Ukraine after recognising them as independent on Monday, accelerating a crisis the West fears could unleash a major war.

A Reuters witness saw tanks and other military hardware moving through the separatist-controlled city of Donetsk after Putin formally recognised the breakaway regions and ordered the deployment of Russian forces to "keep the peace".

About five tanks were seen in a column on the edge of Donetsk and two more in another part of town, a Reuters reporter said. No insignia were visible on the vehicles.
