CARS, aircraft and police officers will be carrying out security exercises around South Wales over the next few days in the run-up to Thursday and Friday's Nato summit at Celtic Manor, residents have been warned.

In a statement, Gwent Police said: "As part of the security operation for the 2014 Nato Wales Summit, a number of exercises involving vehicles, aircraft, and officer deployments will take place in South Wales and the South West over the next few days."

Chief Superintendent Alun Thomas said: "Residents should not be alarmed by these, they are essential to test our procedures alongside our mutual aid policing colleagues and partners from the military.

"We are grateful to the public for their continued support and we apologise in advance for any disruption these activities may cause."
