WASHINGTON (AP) — The chairman of the Joint Chiefs of Staff has asked a Florida preacher to withdraw his support of the anti-Muslim film that may have fueled the fatal attack on the U.S. embassy in Libya.

Gen. Martin Dempsey called Terry Jones Wednesday morning to express his concerns about the film, saying it could inflame tensions and trigger violence.

Dempsey spokesman Col. Dave Lapan said Jones did not say whether he would limit or continue his backing of the movie, "Innocence of Muslims." Video excerpts have been available online.

Jones' call to burn Qurans in 2010 triggered Pentagon worries that it could endanger the lives of U.S. troops in Afghanistan and Iraq. He called off the burning, but his discussions triggered unrest in Afghanistan.
