Detailed Summary
On January 27, 2026, Switzerland released a press statement regarding the fifth report of the Investigation and Identification Team (IIT) of the Organisation for the Prohibition of Chemical Weapons (OPCW). The report documents a chemical weapons attack in Kafr Zeita, a village approximately 30 kilometers north of Hama in the Syrian Hama Governorate.
The IIT concluded that there are reasonable grounds to identify the Tiger Forces of the Syrian army as perpetrators. During a military offensive to counter opposition advances, Syrian Air Force helicopters dropped at least one yellow pressure cylinder. It struck two ventilation openings near the Al Maghara Hospital and released chlorine gas, which spread and injured at least 35 people.
Switzerland emphasizes that the absolute prohibition of chemical weapons applies without restriction – at all times and under any circumstances. The report is assessed as further evidence of systematic use of toxic chemicals against the civilian population by the former Syrian authorities.
Switzerland actively supports criminal prosecution through multiple mechanisms: the IIT, the International, Impartial and Independent Mechanism for Syria (IIIM), and Syrian non-governmental organizations. It welcomes the cooperation of the Syrian transitional government with the OPCW and the IIT.
