A military government also introduced a national cleaning campaign during the civil war.
Even today, military police dressed in camouflage roam the streets stopping errant vehicles and police say everyone must take part.

"If we find a vehicle passing we arrest them, or we make the people in the car come down to do the cleaning. But most people work and are happy to do it."
