A local councillor warns the operation to deal with the apparent “historic piece of munition” could take at least five days to resolve.
Hundreds of homes have been evacuated in Northern Ireland after a suspected Second World War bomb was discovered.
The “suspected historic piece of munition” was found on Friday at the Rivenwood housing development in Newtownards.
On Sunday, the Police Service of Northern Ireland evacuated around 450 nearby homes as they warned the operation “will continue for a number of days”.
Local councillor Pete Wray confirmed it was a suspected Second World War bomb and described the situation as “complex”.
He added that it would likely take at least five days to resolve.
An emergency support centre for affected residents is operating at the Ards Blair Mayne Leisure Complex.
