Traces of sarin found after attack in northern Syria, says chemical weapons watchdog

The global chemical weapons watchdog has said it found traces of sarin following an attack in northern Syria in late March, days before a deadly strike using the same nerve agent in another Syrian town.

The Organisation for the Prohibition of Chemical Weapons said on Thursday that tests had revealed traces of "sarin or sarin-related chemicals" in Ltamenah after an attack on March 30 which injured 50 people.
