DHAKA - A football-mad farmer in Bangladesh has unfurled a homemade German flag stretching 5.5 kilometers in a bizarre act of devotion to his favorite team ahead of the World Cup. Amjad Hossain's long love affair with Germany began unusually - he credited homeopathic medicine made in the European powerhouse with treating a gallbladder stone, and never looked back. In 2006, when Germany hosted the World Cup, he started the black, red and yellow banner and has added to it every tournament since, selling another plot of farmland this year to buy enough fabric to extend the flag by another two kilometers. The 69-year-old unveiled the lengthy tricolor flag with the help of dozens of volunteers at a school in Magura, southwest of the capital Dhaka, before German embassy officials and hundreds of curious onlookers. "The 5.5km-long German flag encircled the school ground several times. Amjad Hossain sold his property to make such a huge flag. He is a genuine German supporter," said Magura deputy police chief Tarikul Islam, who attended Wednesday's ceremony. Bangladesh is gripped by World Cup fever every four years, when its love of cricket is set aside and flags deck the streets, with Brazil and Argentina particular favorites. If Germany advance to the second round of the World Cup, Hossain plans to use the flag to drape his local stadium in the country's colors. "I love German football. They play beautiful football," he said. - AFP
