Now, Pakistan has recalled its ambassador to Iran in response to a missile and drone attack on its territory. Tehran's envoy has also been blocked from returning to Islamabad. Iranian state media say the strike targeted a militant group in the sparsely populated province of Balochistan. But the Pakistani Foreign Ministry said that two children were killed in the attack. A spokesperson called it a blatant breach of Pakistan sovereignty and accused Iran of violating international law. Well, our correspondent, Caroline Davis, is following developments from Islamabad.

Skirmishes between Pakistan and Iran on their border are not unheard of, but they're rarely as high profile as this particular incident. Iranian state media said Yesterday that the Iranian military had hit and targeted the headquarters of a Sunni militant group that is known as Jaesh Al Adil, which has carried out multiple attacks inside Iran, including claiming responsibility for an attack on a police station in December. Now, the group itself has put out on social media. It says that this particular strike hit the homes of the militants and that killed family members of the militants rather than their bases themselves. They have also vowed revenge on Iran. Iran itself has not put out an official statement on this incident. Now, Pakistan's Foreign Ministry has said that two children were killed, and they have called this an unprovoked violation of Pakistan's airspace. Pakistan Iran has now recalled its ambassador to Iran, and it has told that Iran's ambassador to Pakistan, who's currently out of the country, not to return. Of course, the backdrop to all of this, and the reason why this is getting even more attention, is because of the timing. The fact that Iran has also, in the recent days, hit both Iraq and Syria.

Now, put together, this suggests that Iran is currently trying to show a display of strength and force against any group that it considers to be a threat.

Well, I spoke to Hina Raubhani Kha, former Foreign Minister in Pakistan, and asked her if she thinks this is an isolated incident or if it's the start of a larger campaign.

I think this is a reaction to appease domestic impulsion. It's perhaps Iran having compromised its national interest for the sake of the regime's interest. What we see, so I'm much less concerned. I think you should ask me the question, what should be Pakistan's reaction? I think I'm rather happy with the fact that Pakistan is playing the long term. Pakistan has had a very strained diplomatic reaction, we think, in a country which can go up the escalation ladder so quickly. There's absolutely no need to have ambassadorial representation. We have called in back our ambassador. We have asked them to let their ambassador remain there. You know what is very interesting is as we speak, we've had a CT dialog a few days back, a counterterrorism dialog. In fact, today, we were supposed to have a border mechanism commission which was supposed to meet. We have There are two naval ships over there. I'm just saying all of this to show how very, very, how unexplainable or without any context or without any provocation from this side or without any… You do know that the only two people who've been killed in this are two children, and many other children or a few other children have been injured.

So it's really, I think, the intense backlash.

We mentioned your own background.

Domestic- Domestic- The attacks- Sorry, we just had a slight break, and I'm so sorry.

We mentioned your own background and experience, obviously, as a former foreign minister. What would you be doing right now, both in terms of relations and conversations that you'd be having, but also to reassure the population of people in Pakistan as well.

The reaction in Pakistan, I think, currently has been very restrained. I am somewhat happy. A military strike does not have to be retaliated by a military strike. Only an irresponsible nation would do that. However, I think the normalization of relations now would be in Iran's quote, in fact, for Pakistan not to do a military reaction, which is absolutely capable of doing. So please bear in mind, this is not a matter of capacity, it's a matter of choice, and it's a matter of not going up the escalation ladder. I think if the responsibility of holding relations stable only falls on one neighbor, then something might give way. So I would be very keenly looking at the reaction, Perhaps an apology, perhaps you make a mistake. I think them doing this with Pakistan is absolutely unexplainable. It is provocative, it is irrational. I think they should do some deep soul searching because right now, they have very few friends in the world. As I said, Pakistan has made it its prerogative and its responsibility as a neighbor to try and normalize for them the region and the world's relations as much as possible. I think they lost a friend, and I hope they understand the repercussions, both perhaps, hopefully not militarily, which we're fully capable of doing, but at least diplomatically.

Because this is not normal, taking a snipe at somebody's sovereignty and going against international law and making the case of, Oh, we were only going against Iranians. We know that we have an Indian agent who was working from Iranian soil. We have immense examples of things like this. But to sort these issues out in the mechanisms that you have, that is what responsible, stable countries do. We hope that better sense will prevail. The restraint that Pakistan is showing cannot be a forever restraint. But I would hope that this restraint will pay off and better sense will prevail.
