Security forces are out in force across Sri Lanka with orders to shoot looters on sight amid continuing protests at the governments handling of a devastating economic crisis. Despite a nationwide curfew, there was a second night of arson attacks. Shops near Colombo were torched, as well as a resort owned by the son of ex-Prime Minister Mahinda Rajapaksa. The ex-PM is holed up in a naval base after resigning when public fury erupted over fuel and food shortages. At least nine people have been killed and about 200 injured in unrest since Monday. It began when government supporters attacked protesters who are demanding that President Gotabaya Rajapaksa, the former PMs younger brother, should leave office. The worst trouble overnight was in the north of the capital, Colombo, where rival groups set fire to shops in the town of Negombo. Sri Lanka had already seen weeks of protests over its dire financial situation, which has caused the Sri Lankan rupee to plunge, provoking severe shortages of basic items such as food, fuel and medical supplies. On Monday night, mobs burned more than 50 houses belonging to politicians, while a controversial museum dedicated to the Rajapaksa family was also razed to the ground in their traditional heartland, Hambantota, in the countrys south. Shops, businesses and offices are shut for a third day on Wednesday under a nationwide curfew in place until Thursday morning. A meeting between Sri Lankas political party leaders has been moved online over security concerns. The streets of the capital, Colombo, bear the evidence of this weeks rioting - a heavy police presence, troops on the streets, and overturned and burnt buses after Mondays violence. Police have been ordered to shoot law-breakers and looters on sight, while thousands of members of the security forces have been deployed to patrol the streets. Nonetheless, protesters continue to gather at Galle Face Green, the main protest site in Colombo. They insist President Rajapaksa has grossly mismanaged the economy and must stand aside. He is the last Rajapaksa family member in office and the resignation of his brother as prime minister did nothing to placate demonstrators or bring calm. President Rajapaska says he is holding talks with other political parties aimed at forming a unity government. But the main opposition says it will not be part of the interim administration unless the president stands down. At present, there is no clarity on which political parties might come together to form such a government. The political stalemate comes as Sri Lanka attempts to iron out a bailout package with the International Monetary Fund (IMF) - the islands $81bn economy is near bankruptcy. It has suspended its foreign debt payments, largely because it cannot service loans from China that paid for massive infrastructure projects. While the pandemic hit the vital tourism sector and shrank Sri Lankas earnings and foreign exchange reserves, experts say problems have been exacerbated by populist tax cuts in 2019 and a disastrous ban on chemical fertilisers in 2021 that devastated crop yields. Protesters gathered in front of Trincomalee Naval Base in the north-east after reports that Mahinda Rajapaksa had fled there with his family after escaping from his Colombo residence when it was besieged by crowds on Monday night. Defence officials confirmed on Wednesday that he was inside the base. Earlier, there had been rumours that he and others in the family had fled to India, which the Indian High Commission in Colombo denied.
