BEIRUT (AFP) - Thousands of people defied a government ban and massed in the heart of Beirut as Lebanese parliament held a stormy debate set to culminate in a vote of no-confidence in the pro-Syrian regime.  The anti-Syria rally came exactly two weeks after the assassination of ex-premier Rafiq Hariri which triggered a wave of public opposition against the Lebanese government and its backers in Damascus who are blamed for the murder. Waving large red and white Lebanese flags and shouting "Syria out!" protesters descended on Martyrs' Square where Hariri is buried as hundreds of heavily armed troops and police guarded surrounding streets but did not prevent the rally.

By Lucy Fielder BEIRUT (Reuters) - Lebanon's Syrian-backed government banned protests planned for Monday but a main opposition figure vowed the Lebanese would take to the streets to demand who killed former prime minister Rafik al-Hariri. Interior Minister Suleiman Franjieh called on security forces in a statement on Sunday "to take all necessary steps to preserve security and order and prevent demonstrations and gatherings on Monday." Opposition groups have called a protest at the central Martyrs Square by Hariri's grave and a one-day strike to coincide with a parliamentary debate on the killing that for many recalled Lebanon's bitter 1975-90 civil war.

By BASSEM MROUE, Associated Press Writer BEIRUT, Lebanon - A visiting senior U.S. State Department official on Sunday brushed off accusations Washington's calls for Syria to leave Lebanon as soon as possible amounted to interference in Lebanese internal affairs.  David Satterfield, a U.S. deputy assistant secretary of state, was scheduled to meet Foreign Minister Mahmoud Hammoud to convey the U.S. demand for a full and immediate withdrawal of Syrian forces from Lebanon and the need for a thorough inquiry into the assassination of former Prime Minister Rafik Hariri. Satterfield, pressed after a meeting with Cardinal Nasrallah Sfeir, head of the Maronite Catholic Church, about whether Washington considers there to be a deadline for a Syrian withdrawal from Lebanon, said: "We want to see it take place as soon as possible."

WASHINGTON (AFP) - The murder of their former prime minister has united the people of Lebanon behind ending a 15-year Syrian occupation, a top US Mideast diplomat said, pointing to such a move as overdue. In response to Rafiq Hariri's slaying 11 days ago, Lebanese demonstrators demanded Syria withdraw from the country. Beirut announced Thursday an imminent pull back of Syrian troops to the eastern Bekaa Valley near the border. "The assassination, the terrorist murder, of prime minister Hariri has had a very significant impact," US deputy assistant secretary of state for Near Eastern affairs David Satterfield told US-funded Alhurra television.
