United Nations: Kofi Annan, the UN-Arab League joint special envoy for Syria, has said that his six-point peace plan to end the Middle East country's 16-month crisis had not been implemented, Xinhua reported.
The plan is widely backed by the international community and officially accepted by the Syrian government.
Annan was speaking Thursday at the UN General Assembly on the latest situation in Syria.
His peace plan calls for the withdrawal of heavy weapons and troops from population centres, a daily halt in fighting for the delivery of humanitarian aid and treatment for the wounded, as well as talks between the government and the opposition.
Violence could not be allowed to become part of ordinary life in the country, said Annan, adding that both -- the Syrian government and the armed opposition -- had failed to carry out the six-point plan.
"Today, despite the acceptance of the six-point plan and the deployment of a courageous mission of United Nations observers to Syria, I must be frank and confirm that the plan is not being implemented," Annan said.
The former UN secretary-general had met with Syrian President Bashar al-Assad late in May to discuss the country's situation.
Annan said he told Assad during the meeting that "the six-point plan is not being implemented as it must," and strongly urged the Syrian leader to "take bold and visible steps to now radically change his military posture and honour his commitments to the six- point plan."
"If things do not change, the future is likely to be one of the brutal repression, massacres, sectarian violence, and even all-out civil war," Annan warned. "All Syrians will lose."
