United Nations-Arab League envoy Kofi Annan urged President Bashar Al-Assad of Syria to immediately implement a ceasefire amid reports that at least 33 people were killed Friday across Syria according to dpa. Annan's plea came as reports of heavy shelling in the central province of Homs and the northern area of Idlib near the Turkish border were circulated. "The deadline is now," said Annan's spokesman Ahmad Fawzi, three days after announcing that al-Assad had accepted the peace plan. "We expect him to implement this plan immediately. Clearly we have not seen a cessation of hostilities on the ground. This is our great concern," Fawzi said in Geneva. Annan's plan calls for a ceasefire, to be monitored by UN observers; access to humanitarian services; and talks between the government and the opposition.
