Police in Egypt continued to fire tear gas and rubber bullets at protesters occupying Cairo's Tahrir Square as clashes spilled into a second day on Sunday. More than 900 people have been injured, and thirteen have been killed, according to Egyptian doctors. "The violence yesterday shows us that Mubarak is still in power," one demonstrator told the AP, referring to the longtime leader thrown out in a revolt this year. Demonstrators are unhappy with the military regime that has "temporarily" taken over power amid controversy ahead of parliamentary elections. The police arrested 18 people and promptly transferred them to a military prosecutor.
