Port-au-Prince is no longer a capital. It is now a war zone under the reign of brutal gangs.

Almost four years after Haiti's president was assassinated in his own bedroom, the country has spiralled into complete collapse.

Heavily armed gangs now control an estimated 90 per cent of the capital city.

The streets are littered with bodies, hospitals are burning, and children are being raped and recruited as soldiers. The state has all but disappeared.

Gangs now wield more power than the government, according to senior United Nations officials, and they rule with unspeakable brutality.
