Lebanon tense during unity talks

Syrian President Bashar al-Assad and King Abdullah of Saudi Arabia are visiting Lebanon after pledging to work together to help stabilise the country.

It is the first time President Assad has been in Lebanon since Syria was implicated in the 2005 assassination of the Lebanese former PM Rafik Hariri.

A UN tribunal is rumoured to be ready to indict members of Hezbollah for the killing.

But with the group part of Lebanon's fragile unity government, there are fears such a move could cause fresh sectarian violence.
