Turkey is approaching the halfway mark in the construction of a new security wall along its eastern border with Iran.

Turkey began construction of the 144-kilometre-long barrier in August as a means of blocking cross-border movement. 

Turkish authorities say the wall will help them better combat smugglers as well as the PKK terror group.

The Turkey-Iran wall is in addition to its existing wall on the country's southern border with Syria.
