Leeds city centre road closures for 'disaster' training
Road closures were put in place in Leeds as emergency services took part in a major disaster training event.
It was part of a national series of exercises ensuring cities are ready for chemical, biological, nuclear or radiological incidents.
The council also took part in the training, which was based around the process of decontaminating people affected by such an incident.
City centre road closures were lifted at 14:00 GMT.
Ch Supt Christopher Hardern, of West Yorkshire Police, said: "Training exercises like this provide a valuable opportunity for the emergency services and other agencies across West Yorkshire to refine our ability to deal with a major incident."
