International peace mediator Kofi Annan is set to arrive in Damascus Monday. This will be the former UN Secretary General's first visit since early March when he presented his peace plan to the Syrian government.

Annan's spokesman has repeatedly said that a Syrian visit would happen when the time was right. Annan's six points peace plan called for a truce, withdrawal of troops and heavy weapons from cities, deployment of a international observers, and dialogue between the government and opposition aimed at a Syrian-led "political transition."

The now six-week-old ceasefire plan has so far failed to stop the violence. The UN says at least 108 people, including 49 children and 34 women, died in Friday's attacks in Houla.(Xinhua)
