The Irish Republican Army said it planted a bomb near a Belfast elementary school but did not detonate it because there were civilians nearby. Belfast police, however, said the operation was abandoned because the bomb was discovered by a security patrol. The IRA is fighting to end British rule in Northern Ireland and unite it with the Irish Republic. The IRA statement came three days after an IRA bomb killed 11 people and wounded 63 at a ceremony for war dead in Enniskillen, 10 miles from the Irish border. On Tuesday, police defused an explosive device five times the size of the Enniskillen bomb. The 150-pound bomb was found along the route of a second war-memorial ceremony, at the nearby border town of Tullyhommon.
