The UN special envoy, Kofi Annan, has told the Security Council that Syria is still witnessing unacceptable levels of violence, despite a ceasefire being in place since 12 April.

Briefing diplomats in a closed-door session, Mr Annan said he was alarmed about surges in violence in Syrian cities after visits by UN monitors.

One activist group said 38 people were killed on Tuesday, mostly in Homs.
