N. IRELAND . . . AN ULSTER REPLY

Protestant militants sent their contribution to the peace process in Ireland: a bomb on a Dublin-bound train from Belfast. Two women were injured when it partially exploded as the train stopped at its destination. The outlawed Ulster Volunteer Force claimed responsibility and in a statement warned that "Northern Ireland is still British and will not be coerced, forced or persuaded into a united Ireland." This is the third attack by Protestants since the cease-fire was announced a week ago. The I.R.A. has not avenged previous attacks, and the governments of Ireland and Great Britain appealed to the group to hold to its truce.
