Six civilians suffered breathing difficulties and other symptoms indicative of poison gas inhalation after an attack launched by Turkey on the Kurdish-controlled enclave of Afrin, local doctors and Syria’s state-run news agency reported on Saturday.

Jiwan Mohammed, a doctor at Afrin’s main hospital, said the facility was treating six people who had been poisoned, who arrived on Friday night from the village of Arandi after it was attacked by Turkish troops.

Another doctor, Nouri Qenber, said the victims suffered shortness of breath, vomiting and skin rashes. One of the victims had dilated pupils, he said, quoting one of the rescuers.

State-run news agency SANA and the Britain-based Syrian Observatory for Human Rights monitoring group also quoted local doctors in their reports.

The claims could not be independently verified, and videos released from the hospital showed people being fitted with oxygen masks who did not otherwise show symptoms of poison gas inhalation such as twitching, foaming at the mouth or vomiting.

A White House official said the United States was aware of the reports but could not confirm them, and thought it was “extremely unlikely” Turkey had used chemical weapons against the Kurds. The official called for the protection of civilians.

SANA said on Saturday that Turkey fired several shells containing “toxic substances” on a village in Afrin on Friday night, causing six civilians to suffer suffocation symptoms.

The Turkish military repeated in a weekly statement published on Saturday that it does not use internationally “banned ammunition” in its Afrin operation and said “the Turkish Armed Forces does not keep such ammunition in its inventory”.

The army also said it was careful to not harm civilians and only targeted “terrorists” and their positions in the Afrin region.

The Turkish military launched an aerial and ground offensive on Afrin, in north-western Syria, on January 20.

It says the aim of the operation is to push out the Kurdish militia known as the People’s Protection Units, or YPG, from the enclave.

Turkey considers the group to be a terrorist group and an extension of the Kurdish insurgents it fights inside Turkey.

In a separate statement on Saturday, the Turkish army said one soldier was killed in the Afrin operation on Saturday, bringing the overall military death toll to 32 since the start of the campaign.

Another soldier was killed in Turkey’s south-eastern province of Hakkari during clashes with Kurdish militants, it added.

Turkey’s president also said some 60 Turkish-allied Syrian opposition fighters were killed since the beginning of the operation.
