The US and Russia have unveiled a plan aimed at ending the Syrian civil war and leading to political transition in the country.

The agreement calls for a nationwide ceasefire to begin on 12 September - the start of the Muslim Eid al Adha holiday.

If the cessation of hostilities holds for seven days, it will be followed by an unlikely military partnership between the US and Russia to target Islamic State and al Qaeda.

The Syrian government has told Moscow it is prepared to comply with the deal.
