Hundreds of thousands of Egyptian football fans have taken to the streets after Egypt's victory in the Africa Cup of Nations football tournament.
The Pharaohs beat Cameroon in Accra, the Ghanaian capital, to retain the cup they won on home soil two years ago.
Sunday's 1-0 victory means Egypt has now won the cup a record sixth time.
Within seconds of the final whistle being blown, the Egyptian capital erupted into a cacophony of noise and a blur of light, our correspondent said.
Tour boats on the Nile sounded their horns in time to the chants of crowds pouring across bridges spanning Africa's longest river.
Fireworks lit up Cairo's night sky as jubilant fans climbed atop buses and cars, dancing and beating drums.
In Giza, the massive eight-lane Arab League street was brought to a standstill as flag-waving crowds celebrated the Pharaohs' historic victory.
With people driving around and around roundabouts honking their car horns, some policemen joined in the festivities, the BBC's Ian Pannell reported from Cairo.
In the football-loving nation of 80m people, the celebrations are likely to continue for days to come, our correspondent adds.
