The G9 alliance of gangs has for nearly a month been preventing trucks from reaching the Varreux fuel terminal outside Port-au-Prince, leading to shortages that have forced hospitals, businesses and schools to limit operations. But he added that if Henry did not resign in that period, the gangs would take other actions, without elaborating. Many Haitian truck drivers are refusing to transport fuel due to the constant threat of kidnappings by gangs. Canada said late on Thursday that it was withdrawing non-essential personnel from its embassy, citing security problems that are being exacerbated by fuel shortages. Henry last month said the government had organized police escorts to ensure the security of fuel delivery trucks.
