An eruption of protests, big and small. In fact, 24 hours ago, in five countries around the globe, tonight, more than 30 countries. Two more u.S. Embassies stormed, even the new president of egypt, a member of the muslim brotherhood now calling for calm in his country. Abc's lama hasan is on the ground in cairo tonight. Lama? Reporter: David, that anger and those protests are flaring up again tonight. The protectoll us or thes are seething with anger, all aimed at america. In cairo today, the u.S. Embassy under siege. Running battles between protesters hurling rocks and security forces firing back tear gas and water cannons, using a newly erected concrete wall to defend the embassy. What is it that you want right now? A promise from the american government that that will not happen the next year or any other year anymore and all governments stop disrespecting muslims. Stop disrupting our religion. Reporter: It is fury fueled by that online movie mocking the prophet muhammad. In tahrir square right now, we have crowds gathering. They are carrying the islamic declaration of faith, "there is no god but allah and muhammad is his prophet." Today, the protests spread across the globe. In sudan protestors stormed the u.S. Embassy before being stopped. This after setting the german headquarters on fire. In tunisia, black smoke billowed from the u.S. Embassy after protestors attacked it. Two protestors killed. In yemen, the crowds torched. In lebanon, crowds torched a kfc restaurant and broke the windows of a hardees. All this just as the pope arrived to the region, spreading a message of peace and tolerance. Back here in cairo, it is clear the violence could have been worse. After president obama called egypt's new leader mohammed morsi, morsi reversed course and urged the protesters to hold off, saying, "it is required by our religion to protect our guests and their homes and places of work. So I call on you all to consider this, consider the law, and not attack embassies." Not all the protesters are listening to the president's call for calm. Tonight, near the u.S. Embassy, street battles rage on. David? La ma hasan, thank you.
