Lebanon swerved closer to a factional conflagration Thursday night, Jan. 20, when Saad Hariri, whose coalition Hizballah toppled eight days ago, announced he would form a new government and so defy the efforts to oust him. Hassan Nasrallah's supporters warned he was leading Lebanon to disaster. Earlier, Lebanese army units stepped up security for Hariri and government institutions and took up positions at Beirut's intersections ready to ward off any Hizballah takeover attempt.
