A United Nations report released on Tuesday says more than 53,000 people have fled Haiti’s capital in less than three weeks, the vast majority to escape unrelenting gang violence.

More than 60% of those displaced are headed to Haiti’s rural southern region.

But this is worrying for the UN.

UN spokesman Stephane Dujarric says humanitarian groups in the rural southern region do not have sufficient infrastructure, and host communities do not have sufficient resources to cope with the large number of people fleeing Port-au-Prince.

The UN International Organization for Migration says the southern region already hosts more than 116,000 Haitians, who previously left Port-au-Prince.

The exodus from the capital of some 3 million people began shortly after powerful gangs launched a series of attacks on government institutions at the end of February. 

Gunmen have burned police stations, opened fire on the main international airport that remains closed, and stormed Haiti’s two biggest prisons, releasing more than 4,000 inmates.
