World | Ireland Irish Militants Issue London Bomb Threat Warning comes day before queen's visit to Ireland By Matt Cantor Posted May 16, 2011 12:05 PM CDT Copied In an earlier incident, the Mall is closed to public as police examine a suspected package found in nearby St. James's Park, which had also been evacuated, in London, Sunday, May 6, 2007.
