A suspected chemical weapons attack in Syria on Tuesday killed scores of civilians and drew an international outcry.
The Syrian Observatory for Human Rights, a U.K.-based monitoring group, said 58 people were killed in the town of Khan Sheikhoun in northern Idlib province, including 11 children. The death toll is likely to rise, it said.
Turkey said it had dispatched 30 ambulances to Idlib following chlorine gas attacks in the northwestern province, the Turkish Anadolu news agency reported. Syrian opposition health minister Firas Jundi put the death toll at more than 100 civilians and said 500 others, mostly children, were affected by the gas.
Turkish President Recep Tayyip Erdogan called the attack 'inhuman" in a call to Russian President Vladimir Putin, Erdogan's office said.
