8. Iran-Pakistan barrier
Length: 434 miles
After 2007 bombing in the town of Zahedan, Iran decided to erect a fence along its border with Pakistan, in order to prevent terrorist attacks in the future and limit drug trade across the border. In a rare occurrence, Pakistan stated that it doesn’t object the fence. Baloch, tribal people who live on both sides of the fence, do mind, as it creates division among them, but neither of the two governments has bothered to ask them.
