More than $13 million in U.S. funding for an international security force helping fight armed gangs in Haiti has been frozen under President Donald Trump's 90-day pause on foreign aid, the United Nations said on Tuesday.

In a significant policy shift, the US has carved out a $40. 7 million exception to Trump's aid freeze, specifically for Haiti's critical security mission.

As hundreds of armed gang members, entrenched in the hills above Haiti’s capital, await orders to attack the last enclaves not currently under their control, the multinational fight to end their terror is being impeded by the Trump administration’s freeze on foreign aid.
