Syria activist: Homs situation 'so bad'

Activists say Syrian forces have shelled the city of Homs and killed more than 200 people - a claim denied by the government.
An activist who is in Homs told the BBC it was an "awful situation".
The BBC has been unable to verify this amateur footage, apparently filmed in Homs. It appears to show chaotic scenes in a mosque, as the injured are treated in a makeshift hospital.
