A Gloucestershire pub and nearby houses have been evacuated after two unexploded devices were found nearby.
Highways staff from the county council discovered the first shell in a stream in the morning while working on a bridge near the Green Dragon Inn, in Cockleford.
Bomb disposal experts carried out a controlled detonation. A second device was found at about 1730 BST.
Police said it was possible there were other World War II devices in the area.
A Gloucestershire Constabulary spokesman said the second device had also been detonated by bomb disposal experts. The first shell was 1ft (30cm) long.
He said crews would not be able to carry out a search until daylight and officers were guarding the spot over night.
The spokesman said the devices, believed to be from World War II, were found by highways staff digging under a bridge that goes over a weir.
He said officers evacuated the pub and a couple of houses as a precaution.
A spokesman from the Green Dragon Inn said said police had closed the road and customers had been asked to leave when the first shell was discovered.
He said: "We were allowed back into the pub about 1700 BST but we were told to vacate the premises again from 1830 BST to 1900 BST because they found another one."
The pub reopened for business at about 1900 BST, he added.
