>> A US Russian truce holding in southwestern Syria on Sunday. A war monitoring group and a rebel official saying there had been no airstrikes or clashes since the truce came in to force at noon local time. It was announced afer US president Donald Trump and Russia's Vladimir Putin met at the G20 Summit on Friday.
They've taken opposite sides in Syria's war. Moscow backing Damascus, the United States his opponents. But they worked together when it comes to fighting Islamic State. Jordan which borders the area also helped to reach the deal. It was Trump's first foray into peace making in Syria's civil war. A round of UN brokered peace talks opens in Geneva on Monday.
Syrian President Bashar al-Assad's forces have gained on the rebels over the past year, backed by Russian air power. The war has killed nearly half a million people and reduced swathes of cities to ruins. The southern de-escalation zone is meant to enable humanitarian access and pave the way to a more robust ceasefire.
But it's not clear how committed the fighters on the ground are to the deal and many a truce has crumbled since war broke out six years ago.
