Chaos and suspicion in a Ukrainian city spinning out of control

MARIUPOL Ukraine (Reuters) - Tossing his spanner to the ground, the man in a red beret and bomber jacket lowered himself into the captured armoured personnel carrier (APC) and began to turn and tilt its 50 mm gun.

Behind him, barricades of garbage bins and wooden pallets blocked every entrance to the central square of the eastern port city of Mariupol, after a day of gunfire and death that took Ukraine one step closer to civil war.
