Diplomatic personnel around the world received warnings that diplomatic facilities are now on “high alert” for attacks that could avenge the killing of bin Laden, Bloomberg reported.

“They want to avenge this,” Rep. Peter King (R-N.Y.), chairman of the House Homeland Security Committee, told Fox News.

Ronald Noble, secretary general of international policing group Interpol, also said attacks were possible. “In the immediate term, there will be some retaliation,there will be some revenge attacks,’ he said. “In the long term, the world will be much safer without bin Laden.”
