Violent Clashes between Police, Protesters in Tahrir Square

More than 1,500 people have been wounded and 23 killed as protesters take to the streets of Egypt once again. That country's military rulers are facing the most sustained challenge to their hold on power since demonstrators forced former president Hosni Mubarak from power last February. In cities across Egypt, protesters are calling for an accelerated end to the military ruling council that has governed since the fall of Mubarak. But today, the entire cabinet of the interim civilian government submitted its resignation to the council.
