Lebanon's President Emile Lahoud had no contact with a suspect named by a UN inquiry into the killing former Prime Minister Rafik al-Hariri, the presidential office said on Friday. "The press office in the presidential palace categorically denies this information, which has no basis in truth and is a part of pressure campaigns against the president," it said in a statement. UN investigators reported on Thursday that a suspect had called Lahoud minutes before a truck bomb killed Hariri and 20 other people in Beirut in February. "It is a damning report for President Lahoud and his top aides. He must accept the consequences and resign," said MP Elias Atallah, who is allied to the movement headed by Hariri's son Saad which commands a parliamentary majority.
