Call Emerges for "Burn the Stars and Stripes Day"

A radical Islamic activist and lawyer in the U.K. has called on Muslims worldwide to burn U.S. flags outside American embassies on Sept. 11, a "direct retaliation" against a Florida church's plan to burn Qurans on the same day.

Anjem Choudary, former leader of the banned hardline Islamic group Islam4UK, told CBS News in London he was calling for, "an international burn the Stars and Stripes day" on the anniversary of the 9/11 terrorist attacks.

Choudary, who regularly organizes small demonstrations in Britain calling for the implementation of Islamic law, was the first public figure -- and a likely one -- to call for retaliation against Gainesville, Fla. Reverend Terry Jones' plans to burn at least 100 Qurans.

Anticipating a volatile reaction from the world's Muslims if Jones' church goes ahead with the stunt on Saturday, the State Department issued a warning to all U.S. embassies on Wednesday advising them to assess their security measures and brace for potential backlash.

Rev. Jones has ignored pleas from the Obama administration and U.S. military commanders to abandon his plans, telling CBS News on Wednesday that he felt the act was still "very necessary" as a warning to Islamic radicals, who he feels are attempting to gain political clout and push their agenda in the U.S.
