By BASSEM MROUE, Associated Press Writer BEIRUT, Lebanon – Screaming and weeping mourners clambered around the flag-draped coffin carrying the body of former Prime Minister Rafik Hariri as hundreds of thousands of people turned out for his burial Wednesday, two days after a huge bomb killed the man credited with rebuilding post-civil war Lebanon. Suspicions over Syrian involvement in Hariri’s assassination further charged the atmosphere, with his family and supporters warning officials of the pro-Syrian Lebanese government to stay away. Internationally, pressure mounted to find his killers, with Washington recalling its ambassador and the U.N. Security Council demanding Lebanon catch bring those responsible for Hariri’s slaying. More than 200,000 people crowded into central Beirut square around the towering Mohammed al-Amin Mosque, which Hariri built. It is also where the billionaire businessman who was Lebanon’s prime minister for 10 of the 14 years following the end of the 1975-90 civil was is to be buried.
