Clinton calls on Assad to reform or 'get out of the way'

US Secretary of State, Hillary Clinton, has called for Syria's President Bashar al-Assad to reform or "get out of the way".

Syrian government troops have heavily bombarded Rastan, near Homs, in the centre of the country, killing at least 15 people, activists say.

More than 50 people have been killed in Rastan since a military operation there started at the weekend, reports say.

Mrs Clinton said the international community needed to unite to increase pressure against President Assad "to end the violence and bring this chapter to an end".
