On Wednesday, Pakistan recalled its ambassador from Iran after an airspace violation by the Iranians in pursuit of targets they say are militant bases.
The airspace violation occurred on Tuesday when Iranian missiles targeted two bases in Pakistan's territory that Iran believes belong to the militant group Jaish al Adl.
Pakistani officials say the attack resulted in the deaths of two children.
Amir-Abdollahian, Iran's Foreign Minister, said Iran hit militants in drone and missile strikes and that no Pakistan citizen was targeted. Pakistan has not confirmed the location of the target nor the nature of the airspace violation.
Iran asserts that only terrorists were hit. Pakistan maintains that the violation was unprovoked and a breach of their sovereignty. The relationship between Islamabad and Tehran has been tenuous for years but this is the highest-profile cross-border incident between the two countries in recent memory.
The strikes in Pakistan came a day after missile and drone strikes in Syria targeting the Islamic State. Pakistan officials say that four missiles hit the Panjgur district, which is located near the border with Iran.
Officials in Pakistan's southwestern province of Balochistan, which borders Iran, said that four missiles had hit the Panjgur district close to the Iranian border.
"Four missiles were fired in the village of Koh-i-Sabaz which is around 50 km inside Pakistan soil," a senior official of the Panjgur administration told Reuters."
A mosque and three houses were reportedly damaged in the attack," another official said, adding that two young girls were killed and three other people injured.
Jaish al-Adl, also known as the "Army of Justice," is a Sunni militant organization founded in 2012 that primarily functions in Pakistan across the border, and has claimed responsibility for bombings and abducted Iranian border police in the past.
Iran and Pakistan have long had a tense relationship, in large part because of the activities of Balochi separatists and other militant groups in the border area.
Although Iran's armed forces are the 14th most powerful in the world, according to The Guardian.
Also, they have mastered the manufacturing of cheap, deadly drone technology, Pakistan is the only nuclear-armed Muslim country on record. They have produced approximately 150 nuclear weapons to date.
