Anti-terrorist detectives were questioning nine suspected Irish Republican Army dissidents Monday over this month's deadly gun attacks on British soldiers and police _ the first in this British territory since Northern Ireland's 1998 peace accord. Sinn Fein deputy leader Martin McGuinness, the former IRA commander who is now the senior Irish Catholic in Northern Ireland's power-sharing government, said he was confident that both sides of the community were uniting against the rising dissident threat. «People are not shaken, they understand this is an attempt to create mayhem in our society, it isn't going to succeed, and the political process is going to continue and ultimately be successful,» McGuinness told reporters during a visit to New York City, according to a report of Associated Press.
