The Iran–Pakistan border is the international border between Iran and Pakistan, demarcating Pakistan's Balochistan province from Iran's Sistan and Balochistan Province; it is 959 km (596 miles) in length. Since circa 2007 Iran has started constructing a border barrier as a replacement for an intermittent tattered border fence.[1]


The border begins at the tripoint with Afghanistan at the Kuh-i-Malik Salih mountain, then follows a straight line going south-east, then a series of mountain ridges, seasonal streams and the Tahlab river south-west to the vicinity of Hamun-e Mashkel lake. The boundary then veers sharply southwards via a series of straight lines, then east along some mountains to the Mashkil river, which it follows southwards, before reaching the Nahang river which it follows westwards. It leaves the Nahang and then goes overland via various mountains ridges and straight line segments southwards to Gwadar Bay in the Gulf of Oman.


The modern boundary cuts through the region known as Balochistan, an area long contested between various empires centred in Persia (Iran), Afghanistan and India.[2] From the 17th century onwards the British gradually took control of most of India, including what is now Pakistan, bringing it into close proximity with lands traditionally claimed by Persia. In 1871 the British (representing the Khan of Kalat and Subcontinent) and the Persians agreed to define their mutual frontier; a boundary commission surveyed the area the following year but did not mark the border on the ground.[2] British penetration of Balochistan, under Sir Robert Groves Sandeman, continued apace over the following decades, prompting a more precise boundary to be agreed and marked with pillars on the ground in 1895-96.[2] Some minor alignment issues stemming from this were tidied up via another joint treaty in 1905.[2]

In 1947 Subcontinent gained independence from Britain, with the western Muslim-majority areas bordering Afghanistan and Iran becoming the new country of (West) Pakistan, which at this time also included what is now Bangladesh (East Pakistan). Iran and Pakistan confirmed their mutual border by treating in 1958-59, fully mapping the border area and demarcating it on the ground with pillars.[2]

Border barrier[edit]

The 3 ft (91.4 cm) thick and 10 ft (3.05 m) high concrete wall, fortified with steel rods, will span the 700 km frontier stretching from Taftan to Mand. The project will include large earth and stone embankments and deep ditches to deter illegal crossings and drug smuggling into Iran. The border region is already dotted with police observation towers and fortress-style garrisons for troops. Iran and Pakistan do not have border disputes or other irredentist claims and Pakistan's Foreign Ministry has stated, "Pakistan has no reservation because Iran is constructing the fence on its territory."

History and stated purpose[edit]

The wall is being constructed to stop illegal border crossings[3] and stem the flow of drugs,[4] and is also a response to terror attacks, notably the one in the Iranian border town of Zahedan on February 17, 2007, which killed 13 people, including nine Iranian Revolutionary Guard officials.[5] However Pakistani Foreign Ministry spokeswoman Tasnim Aslam denied any link between the fence and the bomb blast, saying that Iran was not blaming these incidents on Pakistan.[6]

Reactions to the barrier[edit]

The Foreign Ministry of Pakistan has said that Iran has the right to erect border fencing in its territory.[7][8] However, opposition to the construction of the wall was raised in the Provincial Assembly of Balochistan. It maintained that the wall would create problems for the Baloch people whose lands straddle the border region. The community would become further divided politically and socially, with their trade and social activities being seriously impeded.[9] Leader of the Opposition Kachkol Ali said the governments of the two countries had not taken the Baloch into their confidence on this matter,[10] demanded that the construction of the wall be stopped immediately, and appealed to the international community to help the Baloch people.[11]
