Damascus: Former United Nations secretary-general Kofi Annan has warned that his peace plan for Syria will not be available ``forever``.
According to The Telegraph, Annan gave the warning after the massacre of another 12 people came to light.
Annan has devised a six-point plan that commands support from the international community and a verbal commitment of both President Bashar al-Assad and the Syrian rebels for peace in Syria.
Speaking in Beirut, Annan called for ``bold action`` by Assad and the Syrian Government to put ``real energy into the implementation of the six-point plan``.
Annan said: "This is not something that can go on forever. It is essential that he [Mr Assad] shows determination and sends a signal for his people and international community that he is determined to implement the plan and move ahead in terms of peace."
Annan candidly admitted that the UN Security Council could call off the peace plan, adding that he was ``more frustrated`` than anyone by the failure to implement his plan.
Annan, who met the Syrian president in Damascus, said: "I know we are all impatient; we are all frustrated by the violence, by the killings. So am I. I think I am probably more frustrated than any of you because I am in the thick of things and would really want to see things move much faster than it has done."
A pro-regime militia killed about 12 factory workers after forcing them get off a bus in the western village of Qusair, according to opposition activists.
