The Norwegian general Robert Mood, who will command a 300-strong contingent of UN observers in Syria, has arrived in Damascus.

The ceasefire that the team is supposed to be monitoring has badly unravelled, with activists reporting more than 500 people killed since it was declared. Both sides are blaming the other for the violence.
