Two British soldiers were killed and two seriously injured in the explosion of a booby-trapped truck that they were inspecting in Ulster. In a message to news media in Belfast, the outlawed Irish Republican Army said its guerrillas had rigged the truck with explosives and abandoned it near an army observation post outside the village of Crossmaglen near the Ireland border. The IRA also claimed responsibility for the death of John McVitty, 46, a member of the Royal Ulster Constabulary. McVitty was killed by a shotgun blast while he and his 12-year old were cutting brush on a farm near the border town of Rosslea. The boy was not hurt in the attack. McVitty was the seventh member of the constabulary killed this year.
