A bomb exploded Saturday in a Tripoli street housing the Algerian, Greek and Saudi embassies, lightly damaging a car, hours after a soldier was wounded in a bombing in Libya's second city Benghazi.

Two men were killed and contact was lost with at least 18 others in the Syrian town of al-Qusayr near the border with Lebanon, LBCI television reported on Thursday.

The Directorate General of Internal Security Forces on Monday denied issuing a memo instructing ISF members not to wear uniform in public in the wake of the deadly clashes that erupted in Tripoli's al-Beddawi on Sunday.

Religious and civil figures from Tripoli on Monday rejected the proliferation of arms in their restive city and condemned the latest calls for “jihad” in Syria that were voiced by Lebanese Sunni clerics.
