The attack, which was carried out by the Syrian regime, killed scores of people and injured many others on Tuesday.

Erdogan met with al Yousef during a visit to the Southern Turkish province of Hatay, a town on Turkey's border with Syria.

Al Yousef kissed Erdogan on the forehead as the president offered his condolences.

The man had also said that, "As Syrians, our brother Recep Erdogan is our only hope," as he made reference to the Turkish president's involvement in the Syrian civil war.

"My children were so beautiful, but they were not the first children who were killed in Syria. We will show all the world how patient we are. We are not the first or the last. The Syrian war will continue. Our children have been killed in our arms for six years. Nothing has been done."

Experts from the World Health Organisation (WHO), along with members of the the Organisation for the Prohibition of Chemical Weapons, (OPCW) have been trying to ascertain what substance was used in the deadly chemical attack in Syria's Idlib province.

They arrived in Turkey several days ago and have been carrying out extensive tests on the bodies of some of the victims.

WHO said initial indications were that the nerve agent Sarin was used.

Family members of the victims are hoping for answers.

Some of the injured, most of them women and children, were brought to Turkey for treatment.
