The United Nations Office for the Coordination of Humanitarian Affairs (OCHA) warned Wednesday that 1.5 million Haitians have no access to basic services as a result of gang fighting in Haiti’s capital, Port-au-Prince.

“1.5 million children, women and men trapped by gang violence in Port-au-Prince, Haiti are denied basic services and freedom of movement. Immediate access is needed for humanitarians to deliver emergency aid,” OCHA Haiti stressed on its Twitter account.

Thus, the agency has called for the violence in Haiti to stop “to ensure the free movement of people and access to basic services,” adding that “the principles of neutrality, impartiality and humanity must be respected.”

In this conflict, armed gangs are fighting for control of Cité Soleil, the country’s largest slum.

The NGO Doctors Without Borders (MSF) warned on Tuesday that thousands of people are isolated without drinking water, food or medical care in the Port-au-Prince neighborhood of Cité Soleil by armed groups vying for control of the area.

Since the assassination of President Jovenel Moise, Haiti’s always convulsive political and economic situation has been further shaken. The power vacuum degenerated into a security crisis, with murders and kidnappings on a daily basis, especially in large areas of the capital.

In addition, the mandate of Prime Minister Ariel Henry officially ended on February 7, which has increased the crisis of legitimacy in the country and the economic problems, amid increasing attacks by various armed gangs.
