An emergency support centre was set up for residents who had to move out of their homes.

Belfast Telegraph journalist Brett Campbell shared a video on Twitter.

He commented: “Police cordon extended at Rivenwood in Newtownards following the discovery of an unexploded 1,100lb WW2 bomb dating back to 1941/42.

“Some residents have refused to leave their homes, and some are unable to do so due to health reasons.”

Police in Northern Ireland ordered the evacuation of more than 400 homes to remove what is what is believed to to be a 1,100lb World War II-era bomb – with some people said to be refusing to leave their homes.

The removal operation could take more than five days, police said yesterday.

The device was discovered Friday in Newtownards, an area of County Down, about 9 miles (15 kilometres) east of Belfast.

“I appreciate the disruption that this has caused, however keeping people safe is paramount and we will not take any risks,” North Down and Ards District Commander Superintendent Johnston McDowell said. “I want to thank those who may be affected for their patience at this time.”

Police had set up barricades and asked drivers to avoid the area.

Prime Minister Sir Keir Starmer is visiting Northern Ireland today.

Alliance Strangford MLA Nick Mathison urged residents affected by the discovery of a suspected WW2 bomb in Rivenwood, Newtownards, to follow the advice offered by the authorities.

He said: “I appreciate that the discovery of a large historical munition in Rivenwood, Newtownards, is of course causing affected residents significant concern. Not only is there the obvious worry about public safety, but the hundreds of households impacted have had to make alternative accommodation plans at extremely short notice. However, it is crucial for everyone affected by this to follow the instructions of the PSNI and the responding agencies for their own safety and the safety of others.

“Ards Blair Mayne Wellbeing and Leisure Complex has been opened as an emergency support centre for residents who have been evacuated. Displaced residents who have no alternative accommodation can go to the centre for shelter and support.

“Residents are requested to plan ahead and bring all necessary items when leaving the evacuated area, as re-entry will not be allowed. Anyone with vulnerabilities due to health, age, or who requires access to medication should also seek help from the Ards Centre, where there is a multi-agency team on site.

“I understand that residents are concerned about pet care, and the Ards and North Down Borough Council is working with local animal charities to assist residents with this. If you require pet care, please get in contact with them for further details.”
