Group in knife attacks against Egypt protesters

Groups of men armed with knives and sticks attacked protesters trying to march to the headquarters of Egypt's military rulers today, setting off fierce street clashes.

The clashes come as tensions have been rising between the military council which took control of the country after a popular uprising forced ex-President Hosni Mubarak and activists who want them to move faster in bringing former regime officials to justice and setting a date for the transition to civilian rule.
