Beneath a gloomy white sky, more than 100 armed police poured into the slum of Badia East in the teeming megacity of Lagos, Nigeria.
As they advanced, they cracked their batons on the unpaved streets and against the ramshackle walls of the shanties.
“If you love your life, move out!” the officers shouted.
Thousands of people grabbed what belongings they could carry and fled.
Then a line of hulking excavators moved in, using their hydraulic claws to smash homes into pieces. Within hours, the neighborhood was a ruin.
