The government is giving Northern Ireland police new power to use a revolutionary crime-detecting technique known as genetic fingerprinting after an IRA bombing killed six British soldiers.

But Prime Minister Margaret Thatcher ruled out a reintroduction of detention without trial to deal without an upsurge of violence by the outlawed Irish Republican Army in the British province.

British and Irish government officials, meanwhile, were meeting in Belfast Friday to discuss ways of stepping up security cooperation in the aftermath of the IRA bombing Wednesday that killed six off-duty soldiers in Lisburn, seven miles southwest of Belfast.
