Crowds boo and yell as the Egyptian President announces that he will not run for a term in September, but will continue to reign until then.

President Hosni Mubarak announced Tuesday he will not run for a new term in September elections but rejected protesters' demands he step down immediately and leave the country, vowing to die on Egypt's soil, after a dramatic day in which a quarter-million Egyptians staged their biggest protest yet calling on him to go.

Soon after his speech, clashes erupted between protesters and government supporters in the Mediterranean city of Alexandria, and gunshots were heard, according to footage by Al-Jazeera television.
