Fans who survived a deadly stadium stampede in the Ivory Coast blamed police Monday for the tragedy, saying security forces provoked the panic by tear gassing people who had nowhere to run. World soccer body FIFA called for a prompt investigation into the stampede Sunday at Abidjan's Felix Houphouet-Boigny arena, which killed 19 people and injured over 130. Tens of thousands of fans turned out to see Chelsea striker Didier Drogba as the home team squared off against Malawi at a World Cup qualifying match. Wwitnesses said as fans tried to get into the stadium, police fired tear gas into the crowd, setting off the stampede.
