Candidates led by the son of slain ex-premier Rafik al-Hariri won all the seats in Beirut in Lebanon's general election on Sunday, a government source told Reuters. "The count is nearly over and it's a landslide for Hariri's list," said the source, who asked not to be identified. Beirut was the first region to go to the polls. Other regions vote over the next three Sundays. --SP 2340 Local Time 2040 GMT
