Syria, which ended 29 years of military presence in Lebanon last month, said yesterday a joint Syrian-Lebanese military committee would check to see if an old Syrian border post was on right side of the frontier. An Arab satellite channel has shown footage of the post near a village in the Bekaa Valley and said Syrian troops were still present in Lebanon. "An official source said that the general command of the army and armed forces has decided in coordination with the leadership of the Lebanese Army to form a joint military committee that includes officers and topography experts to probe this issue," the official Syrian Arab News Agency reported.The agency said the source was commenting on reports that said "a number of Syrian soldiers have crossed the Syrian-Lebanese border in the area of Deir Al-Aashaer and the east of Kfar Kouk". The post has been near the village of Deir Al-Aashaer since before 1976 when Syria rushed troops into Lebanon to help end the 1975-1990 civil war. Some Lebanese say it is about 300 meters inside Lebanon, others say it is in Syria.
