BEIRUT (Reuters) – Voters go to the polls in south Lebanon on Sunday in the second phase of parliamentary elections with the country rattled by the assassination of a prominent anti-Syrian journalist. A slate led by Syria’s allies Hizbollah and Amal groups looks assured of victory in the Shi’ite Muslim heartland bordering Israel but the killing of columnist Samir Kassir on Thursday has again raised the stakes at the polls.The disparate anti-Syrian opposition put some of its differences aside to join voices in blaming Syria and its security allies for the killing and called for the resignation of President Emile Lahoud, a close ally of Damascus.Several opposition figures said his resignation would be the new parliament’s main task after the May 29-June 19 elections. The opposition called on Friday for a gathering at a crossroads leading to Lahoud’s presidential palace on Monday “to declare the responsibility of the chief of the Lebanese-Syrian security regime for the series of assassinations.”
