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.

A source says the threat has some credibility because the caller uttered a codeword known to the police.

The militant group the Real IRA last month said the queen wasn’t welcome in Ireland. Read These Next Meet the Oscar winner who says the award injured her career.
