NORTHERN IRELAND

The IRA’s political wing, Sinn Fein, accepted U.S. proposals outlawing violence and guns in Northern Ireland. But Britain, Ireland and the United States said that was not enough to earn the party a seat at next month’s peace talks. The London, Dublin and Washington governments gave a cautious welcome to a commitment by Sinn Fein leader Gerry Adams to observe principles drawn up by President Clinton’s Ireland advisor, former Sen. George Mitchell. But they made clear that only a new Irish Republican Army cease-fire will win the party, which seeks to end British rule of the province, a place at the talks starting June 10 in Belfast, Northern Ireland’s capital.
