the announcement came about 90 minutes ago, defeating ahmed shafiq. christian amanpour is the global affairs anchor, also with her is correspondent ben wedeman. let s go back to the moment this was announced by effectively the elections commission in cairo. tell me, ben, wareaction imdiate and joyous? reporter: it was incredible. we really heard a rouge roar coming uprom the crowd. the only time i ve heard a louder roar was 6:00 p.m. last year when hosni mubarak s resignation was announced. what we saw it s a very hot, bright day in cairo. i d say tahrir square was about a third full. within about 20 minutes, it just filled up and people continue to fill up in the square coming from all the parts of cairo. as the temperatures become to become a little more mild, i think we re going to hear more fireworks, more car sirens and see more and more people coming out here because this is truly a historic day for egypt where egyptians finally see those who were on the other side
