An explosive device was neutralised by Irish Defence Forces EOD experts in central Dublin, near Merrion Square. Police said they were called on Friday after receiving a report about a suspected device in a business building. The initial assessment led to the deployment of the EOD team from the Defence Forces. Officials said the EOD specialists neutralised what they described as a rudimentary but viable device. Police opened an investigation and did not specify when they believed the device was placed, or provide further details. The discovery came close to a major political event. World leaders had dined the day before at a venue on another side of Merrion Square, as part of a two-day summit in Dublin. Police said the security operation for the summit was the largest the force has ever carried out. The investigation remains ongoing.
