Residents in and around Ashley Road in Boscombe are being advised to keep their windows closed, after a primary school was evacuated because of the presence of an unknown respiratory irritant.

The road's closed and Bournemouth Council says it will be for the foreseeable future.

420 children and a hundred and eighty staff at Kings Park Primary School were sent home this afternoon and the emergency services remain at the site.

Dorset Fire and Rescue says thirty children with conditions like asthma have been tested by ambulance staff but no-one's been taken to hospital.
