Al Jazeera's Rula Amin, reporting from Beirut, says the people of neighbouring Lebanon have little fear that Syria would use its chemical weapons against the Lebanese people. 

Instead, with half the Lebanese population siding with the government of Bashar al-Assad and half against the leadership in Damascus, the Lebanese people have a greater fear that Syria's "sectarian tensions may actually spill into Lebanon ... they feel volatile, they feel vunerable".

Our correspondent also reports an increased number of Syrian refugees arriving into Lebanon, especially from the capital, once thought to be a "safe haven".

Some of them are very rich who come in very expensive cars ... but they all feel the government has become so serious that it is necessary for them to leave and seek shelter in Lebanon.
