On May 27, a convoy of the Turkish military and one of its proxy groups, the Sham Legion, was targeted on the M4 highway in the northwestern Syrian region of Greater Idlib.
As a result of the attack, a Turkish soldier and an officer were severely injured. Turkish military helicopters evacuated service members from the explosion site.
Some sources said an improvised explosive devices (IED) struck the convoy as it was moving on the highway, near the town of al-Gassaneyah. Others claimed that the Turkish convoy was damaged by an explosion at a headquarters of the al-Qaeda-affiliated Turkistan Islamic Party (TIP).
The mysterious large explosion wiped out the headquarters. At least six Ughur members of the TIP were reportedly killed in the explosion.
According to several opposition sources, the Russian Military Police and the Turkish military planned to carry out a joint patrol on the M4 highway on May 27. After the recent incidents, the patrol was apparently canceled.
Turkey committed to open the M4 highway, which links the cities of Lattakia and Aleppo, under the March 5 agreement with Russia. However, this is yet to happen as terrorists are still blocking several parts of the highway.
This was not the first attack on Turkish forces attempting to secure the M4. Last March, a Turkish service member was killed in a similar explosion.
