FJP: 'Treachorous hands' at work in Egypt Fans of Al-Masry team run after players of the Al-Ahly team during riots that erupted after the football match between the two teams in Port Said, 220 kms northeast of Cairo, on February 1, 2012. At least 73 people were killed and hundreds injured in the violence that erupted as soon as the referee blew the final whistle in the match. UPI/Ahmed Gomaa CAIRO, Feb. 2 (UPI) -- Deadly riots on a soccer field in Port Said, Egypt, were the work of "treacherous hands" meant to push Egypt toward chaos, the Muslim Brotherhood said. At least 73 people died and scores were injured Wednesday in the clash between rival fans in Port Said. Witnesses told the BBC some of those killed were stabbed and others died trying to escape the stadium. Police were criticized for their apparent lack of response. The unrest follows the conclusion of tiered parliamentary elections in Egypt, the first since the country's revolution last year. The Muslim Brotherhood's Freedom and Justice Party dominated the post-revolution elections alongside other Islamic groups. The FJP, in a statement, said it believes the Port Said riots weren't about hooliganism associated with fan enthusiasm but "an integral part of a deliberate scheme to ignite strife, originally aiming to push Egypt into a downward spiral of crises." The Islamist group said the events Wednesday can't be separated for a general decline in the state of security in post-revolution Egypt. The FJP said it believed it was more than a coincidence that riots broke out after the completion of parliamentary elections. "This points to treacherous hands which are no longer hidden (and are) intent on forcing Egypt into chaos and destruction," the party said. Field Marshal Hussein Tantawi, head of the ruling military council, was quoted by the BBC as saying "those trying to destabilize Egypt will not succeed."
