Filippo Grandi, who became the High Commissioner for Refugees earlier this month, arrived at the camp in Gaziantep province's Nizip district where some of the near 2.5 million refugees housed by Turkey are staying.

“They want to go back to their country as soon as the peace comes," Grandi told journalists when asked what the families he met had told him.

The Italian diplomat visited a training center for Syrian women and a kindergarten. He also met the president of Turkey's Disaster and Emergency Management Authority, Fuat Oktay.

The Nizip camp is one of 25 around Turkey housing around 280,000 Syrian refugees.

The Syrian civil war has claimed more than 250,000 lives and turned the country into the world's largest source of refugees and displaced persons

Turkey began to build a concrete wall months ago with plans to integrate it with an electronic barrier system.

According to the border security plan, Turkey will increase security by building a concrete wall, digging ditches, road reclamations, developing lighting systems, establishing security cameras, and implementing electric fencing and radar cameras along its 900-kilometer-long border with Syria.

The physical security measures would include a 3.5-meter-high concrete wall with wire fences, security lights and cameras along the 900-kilometer border. The plan also includes the flying of surveillance balloons and building a two-fenced border system with new ditches, according to security sources.

Turkey also continues to establish a physical security system along the border. The SFGS system includes 24-hour surveillance by mobile surveillance vehicles, concrete walls with barbed wire fencing, air support with Unmanned Aerial Vehicles (UAV) surveillance and illumination towers for night time surveillance.

The biggest part of the reinforcement efforts in four out of five border provinces with Syria, Hatay, Gaziantep, Şanlıurfa and Mardin, have already been completed.

The government has already renewed nearly 200 kilometers of wire fencing and set up over 100 kilometers of new fencing on the border.

Moreover, the construction of a 151-kilometer-long wall and 450 kilometer-long ditch is continuing with full speed.

Fourteen people, including a Turk, who were en route to Syria to join the ranks of the Islamic State of Iraq and the Levant, or ISIL, were seized by the Turkish military, said the General Staff. 

The foreigners and a Turkish national were entrapped in the Oguzeli district close to the southeastern province of Gaziantep on Feb.9, before they illegally travelled into Syria to joint the ISIL ranks, said the statement on the official site of Turkey's General Staff.

According to the statement, the foreigners were taken to the Gaziantep police department to be deported to their respective countries, after their testimony was heard by a public prosecutor. The Turkish citizen was released following his testimony.

Another statement on the General Staff’s official site said that a Greek C-130 plane has violated Turkish airspace for two minutes in the Dilek peninsula, West of coastal province of İzmir.
