The attacks this week point to an escalation of violence as the situation worsens and gangs overwhelm security forces, including a multinational force.

At least one U.S. airline on Friday temporarily canceled flights to Haiti’s capital after gang members opened fire and hit a U.N. helicopter flying near the country’s main airport. Spirit Airlines said in a statement to The Associated Press that its daily flight from Fort Lauderdale to Port-au-Prince has been suspended

The United States maintains its strong condemnation against ongoing gang violence aimed at destabilizing Haiti’s government and jeopardizing a future of peace and security for the Haitian people.”
