About 150 French troops arrived in south Lebanon Tuesday, launching a week-long deployment to reinforce the UN peacekeeping mission. About 900 French soldiers had gathered at a temporary camp in Beirut awaiting orders to move south to a base in Deir Kifa, east of the port of Tyre. The first detachment went Tuesday, said French military spokesman Col. Jerome Salle, adding that the remainder of the troops would arrive over the next week. The convoy included 13 armored personnel carriers, four Leclerc tanks and several dozen trucks and jeeps.
