Balochistan is a restive region shared by Iran and Pakistan where security forces on both sides of the border have for years battled militant groups – but which now risks being the subject of escalating tensions between the neighbours.
Both Iran’s southeastern province of Sistan-Balochistan and Pakistan’s western province of Balochistan are the most impoverished regions of their respective countries, vast and arid provinces constantly battling drought, with rampant unemployment.
They are home to the Baloch people, who number overall an estimated 10 million, the majority of whom live in Pakistan including also in the Sindh province, with several million in Iran and a much smaller minority in Afghanistan.
Iran and Pakistan share a border of nearly 1,000 kilometres (620 miles) along the provinces with smuggling activity, in particular of fuel, intense due to the porous nature of the frontier.
The Baloch are Sunni Muslims, which in Iran makes them a religious as well as an ethnic minority, with the dominant religion in the Islamic republic Shiite Islam.
Tensions have long simmered on both sides of the border but have rarely flared, as they have now, with both Iran and Pakistan striking what they call “terrorist” targets inside the respective provinces of the neighbouring country.
Nine people were killed in Pakistani air strikes on Thursday, Iranian state media said, two days after Iran carried out strikes against “terrorist” targets in Pakistan, which left at least two children dead.
There have been attacks inside Iran in recent months by the Sunni militant separatist group Jaish al-Adl (Army of Justice), which is blacklisted by Iran – but also its arch for the United States – as a terrorist organisation.
Eleven police were killed in an attack claimed by the group in the town of Rask in December.
Jaish al-Adl was founded in the early years of the last decade after the disintegration of a similar group, Jundallah, which for years had carried out attacks against Iranian security forces but was weakened after the capture and subsequent execution of its leader Abdolmalek Rigi in 2010.
According to official Iranian media reports, he was arrested in extraordinary circumstances in February 2010 when Iranian fighter jets forced a passenger plane he was travelling on to Kyrgyzstan to land in Iran. He was hanged in June of that year.
On the other side of the border, Pakistani forces have for almost two decades also been fighting the latest iteration of an ethnic Baloch separatist insurgency, which has killed hundreds in attacks targeting security forces, government personnel and ethnically non-Baloch civilians.
Baloch separatists and rights groups say the military’s crackdown on the insurgency has included widespread enforced disappearances and extrajudicial killings.
Since 2014, the separatists have also targeted projects associated with the China-Pakistan Economic Corridor (CPEC), a $58-billion project that is part of Beijing’s Belt and Road Initiative (BRI) and large parts of which run through mineral-rich Balochistan.
Baloch separatists are far from the only group, however, to use the vast and largely ungoverned Pakistani region as a base.
Western governments have in the past accused Pakistan of allowing Taliban leaders to enjoy a haven there while there has also been activity of a branch allied to the Islamic State group.
Iran’s Sistan-Balochistan province faced new instability in 2022 when its residents joined in with nationwide protests that were erupting across Iran over the death of young woman Mahsa Amini in police custody.
While the protests had their spark – the alleged rape of a teenager by a police commander in custody in the province – they reflected nationwide anger and security forces cracked down on the demonstrations.
On September 30, 2022, over 80 people were killed, according to Amnesty, when security forces opened fire on a protest in Sistan-Balochistan’s main city of Zahedan in what became known as its “bloody Friday”.
Activists have long complained the region has been the victim of economic and political discrimination by Iran’s Shiite clerical leadership, with disproportionate numbers of Baloch hanged in executions, in particular on drug charges.
Reflecting the economic impoverishment of the region, many Balochs work as fuel carriers – known as sookhtbar in Persian. They smuggle fuel over the border to Pakistan where it can be sold at a higher price.
Dozens have been killed by Iranian security forces in recent years, according to activists.
Amnesty International said that in 2021 at least 19 percent of all executions in Iran were of members of the Baloch minority.
Baloch on the Pakistani side of the border also complain of being disenfranchised, and of income from the province’s rich natural resources not being adequately spent on local governance and social needs.
