MANAGUA, Nicaragua (AP) — Dozens of shops in the Nicaraguan capital of Managua have been looted as protests and disturbances sparked by government social security reforms continued into Sunday. Human rights groups say at least 26 people have been killed in several days of clashes. Images broadcast by local news media showed looted shops in the sprawling Oriental Market district and at least one Walmart. Police apparently did not intervene, in contrast to what had been a heavy-handed response to the demonstrations, in which dozens have been injured or arrested. State-controlled media blamed protesters for the looting, while critics speculated that it was being allowed in order to pressure the business sector, which has set conditions for talks with the government, including an end to the harsh crackdown. “We are seeing social chaos in Nicaragua provoked by the absence of government leadership, and the crisis has been combined with poverty, and that in any society is a time bomb,” sociologist and analyst Cirilo Otero said. “It is believable that the government is promoting (the looting) to put pressure on private enterprise to give in to dialogue even if the violence does not stop, and the cost could be very high,” he added. From the Vatican, Pope Francis said he was “very worried” about the situation in the Central American nation and joined local bishops in seeking an end to all violence. The disturbances broke out in response to President Daniel Ortega’s effort to shore up the troubled social security system with a combination of reduced benefits and increased taxes.
