According to the Times of Israel:
ANKARA, Turkey — Turkey has begun building a “security wall” along part of its border with Iran, regional officials said Tuesday, in a move aimed at stopping Kurdish separatists. Turkish authorities announced construction of a 144-kilometer (80-mile) long barrier in May as a means of blocking cross-border movements by members of the outlawed Kurdistan Workers Party (PKK). The entire Turkish-Iranian frontier is around 500 kilometers long.
