After days of protests and related violence, concerns are growing that furor over an anti-Islam video could intensify even more Friday -- threatening U.S. interests abroad and at home.

People have taken to the streets in 10 nations and the Indian-controlled region of Kashmir, according to U.S. Sen. Dianne Feinstein, railing against "Innocence of Muslims" and the nation where it was produced, the United States. This outrage, and danger to Americans, could worsen in the coming days, the U.S. Department of Homeland Security and FBI warned Thursday in a joint intelligence bulletin.

"The risk of violence could increase both at home and abroad as the film continues to gain attention," the U.S. agencies said. "Additionally, we judge that violent extremist groups in the United States could exploit anger over the film to advance their recruitment efforts."

American tourists cautious, but undeterred

Worries about Friday, in particular, stem from the fact Muslims hold weekly prayers that day -- and may congregate afterward and march on U.S. diplomatic missions.

"We are in a full-court press at every single one of the posts in the Middle East and anywhere else there is any chance of demonstrations after Friday services to make sure nothing bad happens. And to have the security in place in case bad things do happen," one senior U.S. official said.
