Iran's Defense Minister Brigadier General Ahmad Vahidi says the country is rapidly constructing a fence on its border with Pakistan, Press TV reported.
"Barrier and road construction along the border [with Pakistan] is being carried out in the impenetrable mountainous terrain [in southeastern Iran] with precision and quality," Vahidi was quoted by IRNA as saying on Thursday.
The Iranian defense minister said the border barrier would prevent villains from crossing into the Islamic Republic and would help the region realize its economic potentials.
The Iranian insurgent group Jundullah, which is based in Pakistan's Balochistan province, has reportedly been crossing into Iran's Sistan-Baluchestan province to carry out terrorist attacks.
Jundullah leader Abdolmalek Rigi was arrested by Iranian authorities in February 2010 and executed in June.
