"The Turkish Armed Forces have sent instructions to their border control units on the border to prevent illegal crossings. However, security measures remain insufficient, because the artificial border between Syria and Turkey hampers efforts in refusing entry to terrorists," the border guard said.
He added that militants, terrorists and fugitives have been successfully finding loopholes to cross the Turkish-Syrian border despite Turkish tanks and military being deployed along the border to monitor the situation.
"The fact that some Turkish soldiers are working with [terrorist] groups also creates an obstacle to the efforts to protect the borders from illegal crossings. Some soldiers receive money to turn a blind eye to the entrance of terrorists," the guard pointed out.
The Turkish border control services have been refusing entry to jihadists from Syria but no identity checks are being carried out on individuals attempting to cross into the war-torn country, according to the Turkish border guard.
Considerable parts of Syria have been seized by Daesh jihadists, who have declared a caliphate on the territories under their control. The group is considered to be one of the main threats to global security and is outlawed in Russia and the United States, among other many countries.
Last week, Russian Foreign Minister Sergei Lavrov said Russia continued to see militants cross the border between Turkey and Syria and weapons being smuggled into the war-torn country.
