Syria's opposition is refusing to negotiate with President Bashar al-Assad's government despite losing a key battle.

Syrian government forces have captured the last rebel-held land around the strategic city of Qusayr.

It is a major blow to opposition fighters who were using the area to smuggle men and weapons into Syria.

Some of the wounded from the battle for Qusayr are being evacuated across the border into Lebanon.

It is a dangerous and slow operation that many do not survive.
