Mubarak resigns as leader of Egypt, now it appears the military will take control. Is this success or a subtle failure?
The BBC's Jon Leyne in Cairo said the announcement caught everyone by surprise: all over the city, drivers honked their horns and people fired guns into the air.We can only hope this turns out for the best, and wish the people of Egypt good luck and strength.
