Heavily armed gangs have tried to seize control of Haiti’s main international airport as they exchanged gunfire with police and soldiers trying to repel them. The Toussaint Louverture International Airport was closed with no planes operating and no passengers on site. It occurred just hours after authorities ordered a nighttime curfew following an explosion of violence in which armed gang members overran the two biggest prisons and freed thousands of inmates over the weekend.
