TRIPOLI: Lebanese troops deployed in the city of Tripoli on Sunday after 15 people were killed in clashes between supporters and opponents of Syrian President Bashar al-Assad, local medics said, the deadliest fighting in Lebanon since Syria’s uprising began. Residents said relative calm had returned to the Mediterranean city since the soldiers took up positions around the city at around 0400 GMT, after gunmen exchanged heavy machinegun fire and rocket-propelled grenades. Two people wounded in the fighting died on Sunday, adding to the 13 killed on Saturday. Occasional gunfire could still be heard but was less intense than earlier exchanges. Prime Minister Najib Mikati and other local politicians held a crisis meeting in Tripoli at the weekend and instructed security forces to use an “iron fist” to quell the violence.
