Campaigners deny placing bomb outside Shell HQ in Dublin
Shell to Sea campaigners have distanced themselves from the placing of an explosive device outside Shell's headquarters in Dublin.
The Republic's Army Bomb Disposal Unit carried out a controlled explosion on the device at Corrib House on Leeson Street last night.
Shell described the incident as a "sinister development", but the group opposed to the company's pipeline in Mayo said they were committed to a peaceful public protest from the start of their campaign.
Gardaí have launched an investigation into the incident.
