Less than 48 hours after Iran carried out an air strike on Pakistan, Islamabad responded by hitting targets with the Iranian territory in an operation codenamed ‘Marg Bar Sarmachar’.

On Tuesday, Iran had laun­ched attacks in Pakistan targeting what it described as bases for the militant group Jaish al-Adl in the border town of Panjgur in Balochistan, state media reported, prompting strong condemnation from Islamabad and downgrading of diplomatic ties.

The Iranian strikes were part of a series of attacks carried out by Iran in recent days in Syria and Iraq as a response to recent terrorist attacks on its territory. They have heightened concerns about regional stability, particularly amid ongoing conflicts in the Middle East.

By Thursday, the Inter-Services Public Relations (ISPR) said Pakistan had targeted “hideouts used by terrorist organisations namely Balochistan Liberation Army (BLA) and Balochistan Liberation Front (BLF)” in an intelligence-based operation.

Former foreign secretary of Pakistan, Aizaz Ahmad Chaudhry, wrote in an op-ed for Dawn that the two countries have maintained cordial relations over the decades. “Notably, barring a few irritants, there is no major dispute between the two countries,” he says.

While that is true, making the escalation between the two countries in recent days even more concerning, there have also been instances of hostility along the Pakistan-Iran border.

Dawn.com takes a look at such instances that have taken place in the last decade.
