DAMASCUS, May 11 (Xinhua) -- The Turkish forces are continuing to build a wall around the Afrin area in northern Syria, a war monitor reported on Saturday.

The wall length has exceeded 2 km as the Turkish forces are trying to protect its forces from possible attacks by the Kurdish-led groups in northern Syria, according to the Syrian Observatory for Human Rights.

Afrin enclave had been controlled by the Kurdish People's Protection Units (YPG) and other allied militia groups.

Last year, Turkey spearheaded an operation to dislodge the YPG and took control of the city with the help of its allied rebels in northern Syria.

Several explosions have rocked the city since it fell to the Turkey-backed rebels.

Around 350,000 people were displaced from Afrin when the Ankara-backed rebels took control.
