Syria violence: European leaders speak out
European countries have called for "strong measures" to halt repression in Syria, as its government steps up a campaign against peaceful protests.
France and Italy urged the EU and UN to put pressure on Syria to end its crackdown, and the UK said it was working to send a "strong signal" to Damascus. The US has said it is considering sanctions.
More gunfire was heard in the city of Deraa on Tuesday, a day after troops and tanks were deployed. Richard Galpin reports.
The BBC cannot verify the amateur footage shown, but it is believed to show recent scenes of Syrian unrest.
