Mappleton beach's remaining munitions destroyed

The shells were discovered by a dog walker on Saturday at Mappleton beach.

Further controlled explosions have taken place at an East Yorkshire beach destroying hundreds of munitions exposed by a landslip.

The shells were discovered by a dog walker on Saturday at Mappleton beach.

The beach, near Hornsea, was used as a bombing range by the military during WWII and in the 1970s.

Bomb disposal experts from RAF Wittering in Cambridgeshire carried out between four and eight controlled explosions at about 15:00 BST.

The detonations were aimed at ensuring all the munitions had been made safe, an RAF spokesman said.

He added that "99.9%" of the shells and rockets were spent ordnance and posed no threat to the public.

The first set of controlled explosions took place on Monday

Most of the munitions found on the beach are thought to date back about 40 years.

It is expected that the beach will remain sealed off for some days while the clean-up operation is completed.
