Syrian opposition call on President Assad to resign

Syrian opposition groups meeting in Turkey have called on President Bashar al-Assad to resign immediately, and make way for a transition to democracy.

The groups, which comprise about 300 activists, rejected an offer of dialogue and amnesty.

They said in a communique that Mr Assad should hand power to one of his two vice-presidents, without specifying which, and hold free elections within a year.

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