Authorities in Northern Ireland have banned a planned Protestant march through the Catholic village of Drumcree in the city of Portadown, an annual flashpoint in the Ulster conflict. Authorities want to prevent a repeat of the violence that has accompanied past marches by the unionists. Meanwhile, the peace process has been deadlocked there for weeks over the issue of disarming Catholic and Protestant guerilla forces. President Clinton is urging the parties to find a compromise and in a BBC interview today promised he will do everything he can do to help, as a Wednesday deadline nears.
