UN human rights experts say the Syrian air force deliberately bombed a spring outside Damascus in December, cutting off the water supply for 5.5 million people living in and around the city. The Syrian government blamed rebels for damaging the Ain al-Fijeh spring during the battle for the Wadi Barada valley.
But a new report by a UN commission of enquiry says evidence showed the damage was caused by at least two air strikes. The attack, it concludes, was grossly disproportionate and was a war crime.
The report was published a day before the sixth anniversary of the start of the uprising against President Bashar al-Assad, which evolved into a civil war that activists say has left more than 320,000 people dead(BBC,2017).
