Undercover with Syrian army defectors

The Free Syrian Army is made up of pro-democracy protesters and soldiers who have defected from the Syrian Army.

They are calling on the international community to impose a no-fly-zone and to create a safe area near Turkey.

The BBC's Paul Wood and cameraman Fred Scott were smuggled into Syria from Lebanon, and have spent a week undercover in Homs.

They are the first journalists to have spent time with the Free Syrian Army inside the country.
