Almost all Syrian troops have withdrawn from north Lebanon, leaving only intelligence officers behind.
It is understood they have not yet vacated two major intelligence offices and two military positions in and around Tripoli, but could do so within 24 hours.
All other positions, including a large base at an airstrip, were evacuated overnight and thousands of soldiers and hundreds of vehicles were seen crossing into Syria.
Syrian forces first entered Lebanon in 1976 early in the civil war.
Their numbers have declined to 14,000 from a peak of 40,000, but they had never before left positions in the north.
Syrian troops also continued to return home or move eastwards from the Beirut area in line with a phased withdrawal plan agreed this week amid intense global pressure on Syria.
