The teeth and bones that hold the key to this century’s worst chemical weapons attack

Wael Soulaiman , 42 , was responsible for bringing the bodies of his family to Eastern Ghouta .

Bashar al-Assad was on the verge of losing control with the rebel uprising stretching his security forces to breaking point.

He gambled everything on the West ’s indifference when Assad launched a sarin gas attack in August 2013 .

Around 1,500 died in the immediate aftermath, with countless more dying later.

The UN was granted access to the attack site, and also to Moadamiyah in western Ghouta , where they found surviving pieces of the rockets that transported the liquified gas.

Syria , although currently basking in the hope of a better tomorrow , is not yet seen as stable by the outside world.

Syria 's new security service HTS still conducts raids into neighbourhoods populated by Alawites .

The new government insists these are not reprisals, but simply operations to round up weapons dished out in the dying days of the old regime.

Assad is now a guest of Vladimir Putin in Russia , meaning any process of international justice to hold him responsible for Ghouta might have to take place in his absence.
