Al-Jazeera Video: Inside Story - Is Syria's conflict being fought in Lebanon?

"Around 15 people have been killed and more than 40 others injured in recent fighting in the northern Lebanese city of Tripoli - a large city that sits on a very porous border just 130km from the Syrian capital Damascus. A ceasefire is now in place and although there is no armed presence in the streets but the guns and the fighters have not gone away."
