A large number of armed men have been deployed to market areas in the northern Lebanese city of Tripoli.Lebanon’s army commandos and some airborne regiments were also deployed to the flashpoint city on Saturday. The new development came after a man was killed in a clash between supporters and opponents of Syrian President Bashar al-Assad in Tripoli’s Old Souk area on Thursday. Seven people were also reportedly injured in the clash. The area is practically divided between the supporters and opponents of the Syrian government fighting against the foreign-backed militants inside Syria. Dozens of people have so far been killed in similar clashes in Tripoli. Syria has been gripped by a deadly unrest since March 2011, and many people, including large numbers of government forces, have been killed in the violence.
