"Stop!" a police officer in Somalia's capital yells as a traffic light flashes red. Most of the cars keep going. Angered, he steps into the middle of the road and gridlock follows. Mogadishu recently began installing road signs for the first time, trying to end a culture of "anything goes" on the streets.
"We use sticks to stop cars, but they only listen to gun-toting soldiers," the police officer says.
