DHAKA (AFP) - Bangladesh and India signed two deals to tackle poaching of critically-endangered Bengal tigers from the world's largest mangrove forest, an official said Wednesday. The deals were confirmed after meetings in Dhaka on Tuesday evening between visiting Indian PM Manmohan and his Bangladeshi counterpart PM Hasina. Although the UNESCO-listed, 10,000-square-km Sundarbans forest straddles the two nations, there have been no previous joint efforts by India and Bangladesh to conserve the Bengal tiger. "These two landmark agreements (will) go a long way towards protecting tigers and other endangered animals in the forest," BD's forestry secretary Mesbahul Alam told AFP.
