Soil samples from Syria chemical attack sent to western agencies
Samples will help intelligence agencies establish whether nerve agent came from store of sarin Assad was supposed to surrender
Rescue workers have gathered soil samples from the scene of a chemical weapons attack in northern Syria and sent them to western intelligence officials, who are seeking to determine precisely what nerve agent was used in one of the worst atrocities of the country’s six-year war.
The death toll from the attack on the town of Khan Sheikhun in Idlib province rose to at least 72 on Wednesday, with more than 300 other people harmed. The US, Britain and France all said it was very likely that sarin was dropped on the town.
