A police officer was killed Friday after fans rioted at a game between two Sicilian teams, prompting the Italian soccer federation to suspend all Serie A and B matches this weekend. Fans rioted at the Catania-Palermo match, forcing the game to be temporarily suspended in the 58th minute - with Palermo leading 1-0 - after tear gas filled Catania's Angelo Massimino stadium. The ANSA and Apcom news agencies said the officer died after an explosive device was thrown at him. Federation commissioner Luca Pancalli called an emergency meeting in Rome late Friday, and announced he was canceling all games, the federation said. The federation said that another police officer was in critical condition, and police said dozens of people with lesser injuries had been taken to local hospitals.
