400-Pound Car Bomb Found In Belfast

Irish Republican Army dissidents left a 400-pound (180-kilogram) car bomb outside police reform headquarters in Belfast but the homemade device failed to detonate, Northern Ireland's police commander said Sunday. The explosives-laden car caught on fire but didn't explode and caused no damage to the Policing Board building, where a cross-community panel oversees police operations.

As politicians warned of a rising threat from IRA diehards, four other suspected IRA dissidents were arrested Sunday following a gun attack on police.

Chief Constable Matt Baggott said Saturday night's attempted bombing of the Northern Ireland Policing Board office in Belfast's docklands represented an attack on the province's entire peace process. That process has created a joint Catholic-Protestant government and growing support for law and order, achievements that the dissidents hope to undermine.
