Human rights defense groups in Argentina led by the Mothers of the Plaza de Mayo Founding Line are calling on Argentina's chancellery to withdraw its soldiers as part of the United Nations peace keeping mission in Haiti, citing recent protests against President Martelly where the Haitian National Police along UN soldiers had to use force to disperse violent protesters, the departure of Prime Minister Laurent Lamothe and the reports that are coming out of Port-au-Prince about UN soldiers using deadly force against anti-government protests, leaving at least 4 dead.
United Nations has a peace keeping mission in Haiti since 2004, following the overthrow of Jean Bertrand Aristide, many countries, such as Argentina, Brazil and other Latin American countries, has no taste on expanding military operations in Haiti, they definitely don't want to get entangled into another decade long mission, as the crisis continues to worsen.
