The main opposition Republican People’s Party (CHP) has raised questions over the seizure of chemical material, along with barrels of unidentified cargo, in vehicles which attempted to illegally cross the border from the Turkish side to the Syrian side over the weekend.

“One person has been arrested. Barrels which are suspected to contain chemical material were inside the vehicles. Traffic was from Turkey to Syria. Do not be surprised if a statement suggesting that the arrested person is a Syrian spy comes from the government,” CHP Deputy Chair Faruk Loğoğlu said Nov. 4.

Turkish patrol border units seized around one ton of sulfur in addition to eight sealed barrels, the contents of which were unknown, from a convoy trying to illegally enter the country from Syria on Nov. 2, the General Staff announced in a statement posted on its official website.
