DUBAI - An Islamist group calling itself the Turkestan Islamic Party said a deadly car crash in Beijing's Tiananmen Square Oct. 28 was a "jihadi operation" by its mujahideen or holy warriors, the SITE monitoring service said.The service, which tracks Islamist militant statements, said the party had released a Uighur language audio speech from its leader Abdullah Mansour in which he said such operations were only the beginning of attacks on Chinese authorities.In the attack, a vehicle ploughed through bystanders on the edge of the capital's Tiananmen Square and burst into flames, killing the three people in the car and two bystanders.
