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. (AP Photo/Sang Tan) Irish militants called in a bomb threat targeting central London today, a day ahead of Queen Elizabeth’s visit to Ireland—the first visit by a British monarch in more than a century, Reuters reports. A source says the threat has some credibility because the caller uttered a codeword known to the police. The avenue approaching Buckingham Palace has been closed over a security threat, though officials wouldn’t give specifics. The militant group the Real IRA last month said the queen wasn’t welcome in Ireland. Read These Next JFK granddaughter dies at 35. NFL star Stefon Diggs faces felony charge of strangulation.
