The death toll from an early morning Pakistani missile attack on Iran has risen to nine, the country's state media reported, updated from the previously reported seven.

Earlier, it was reported that at least three women and four children were killed in the Pakistani attack on Iran's southeastern border region of Sistan-Baluchistan.

"Two men were also killed in the missile attack this morning in one of the border villages of Saravan, bringing the death toll to nine," the official IRNA news agency quoted Alireza Marhamati, the deputy provincial governor of the Sistan-Baluchistan province, as saying.

"Pakistan attacked an Iranian border village with missiles," state television earlier quoted him as saying. "Three women and four children were killed in this incident. All non-Iranian nationals."

Iran's Interior Minister Ahmad Vahidi told a TV interview that all the victims "were foreign nationals".

Meanwhile, Iran's Fars news agency claimed, without citing any sources, that those killed were "believed to be Pakistani nationals". Neither the minister nor Fars explained their presence there at the time.

Iran's Mehr news agency previously reported "drone and missile attacks" in the sensitive area and said "several people" were injured.

On the other hand, Iran has summoned Pakistan's charge d'affaires, following the missile strike, as per Iranian local media.

"Following the early morning attack by Pakistan on a border village in Sistan-Baluchistan province, an hour ago the Pakistani charge d'affaires in Tehran was summoned to the Foreign Ministry for an explanation," the official Tasnim news agency said.

Condemning Pakistan's attack in Iran, Iranian Foreign Ministry spokesman Nasser Kanaani said the chargé d'affaires had been summoned to convey Tehran’s protest to Islamabad and provide an explanation about the border attack.

The rocket attack came two days after Iran struck a "terrorist" target in Pakistan, killing at least two children.

On Wednesday, Iranian Foreign Minister Hossein Amir Abdullahian said his government was targeting an "Iranian terrorist group" in Pakistan.

He said the attack was a response to deadly attacks in southeastern Iran by Jaish al-Adl, a jihadist group founded in 2012 and blacklisted by Tehran as a "terrorist" organization.

"None of the nationals of the friendly and brotherly country of Pakistan were targeted by Iranian missiles and drones," Abollahian said.

Pakistan on Wednesday condemned the attacks near the two countries' border, recalled its ambassador to Iran and blocked Tehran's envoy from returning to Islamabad.

On January 10, Jaish al-Adl claimed that an attack on a police station in the southeastern city of Rusk left one police officer dead. The same group carried out a similar attack in December that left 11 police officers dead.

The group announced on Wednesday that it had killed a member of Iran's powerful Islamic Revolutionary Guard Corps, according to IRNA.
