Former Bangladeshi premier Sheikh Hasina Wajed left the country Thursday, one day after she was released from detention on graft charges, airport police said, in an apparent deal with the government. The leader of the Awami League party, who was held on corruption charges for almost a year, left Zia International Airport on a flight for London, said airport police chief Ruhul Amin. "The flight carrying Sheikh Hasina took off at around 8.25 am (local time)," he told Agencies. From London she will travel to the United States to have medical treatment for hearing problems. In a surprise move, Bangladesh's emergency army-backed government gave permission for Sheikh Hasina, who led the country from 1996 to 2001, to be released -- albeit with the graft charges still in place.
