Editor's note: Several protests stemming at least in part from an anti-Islam film produced in the United States are unfolding outside U.S. embassies around the world. Friday's protests follow ones Tuesday at the U.S. Embassy in Cairo and the U.S. Consulate in Benghazi, where attacks killed the U.S. ambassador to Libya and three other Americans.
In Tunisia, protesters have scaled a U.S. Embassy gate and set fire to cars on the property, a journalist there says. In Egypt, the influential Muslim Brotherhood canceled nationwide protests planned for Friday, but a running battle between police and protesters in Cairo continued into its fourth day.
