, western Tunisia August 2, 2013. Tunisian troops exchanged fire with militants near the Algerian border on Thursday, security sources said, three days after gunmen killed eight soldiers in one of the deadliest attacks in decades on the country's security forces. Soldiers had been doing security sweeps since Monday in Mount Chaambi, a remote area where the army has been trying to track down Islamist militants since last December.
