By Lin Noueihed BEIRUT (Reuters) – Lebanon’s pro-Syrian prime minister said on Monday he was determined to forge a national unity government, even though anti-Syrian opposition leaders have refused to join any lineup before general elections. Political divisions deepened over the weekend when the opposition dismissed Syrian-backed President Emile Lahoud’s call for talks after a bomb wounded 11 people in a Beirut suburb, raising fresh fears of a return to Lebanon’s violent past. Opposition leaders instead urged Prime Minister Omar Karami, who resigned last month but was reappointed by parliament to form a new government, to make do without them and quickly pick a cabinet to lead Lebanon to elections due in May. he polls may have to be postponed if the political stalemate persists, but Karami stuck to his guns.
