An eleven-year-old boy who survived a bomb explosion targetting football fans in a viewing centre by suspected Boko Haram Islamists lies on a bed receiving treatment in a government hospital in Damaturu, northern Nigeria on June 18, 2014. An explosion carried out by suspected Boko Haram militants ripped through a viewing centre showing World Cup football killing 21 football fans and leaving 27 others injured from the blast. Residents in the Nayi-Nama area said the bomb appeared to have been hidden in a motorised rickshaw outside the Crossfire venue, where crowds had gathered to watch tournament hosts Brazil play Mexico.
