For the second time in two days, police say a vehicle ignored a warning light at a railroad crossing in the Ukraine and was hit by a train in a fatal accident.
In Wednesday's crash, police say an ambulance was hit by a train outside Kiev, killing a pregnant woman and her husband it was carrying, and injuring the driver and a paramedic.
Police say they believe the driver of the ambulance ignored a red light and the siren of an oncoming train at the crossing.
On Tuesday a crash occurred in eastern Ukraine during which a train destroyed a bus whose driver had ignored a red light at another train crossing, killing 44 people.
Ukraine has a bad road safety record. Drivers routinely ignore traffic rules, while aging cars and roads are badly maintained.
