Pakistan said on Tuesday the airspace violation, which Iranian state media said came as Iranian missiles targeted two bases of the militant group Jaish Al Adl, had resulted in the deaths of two children.

Iran's Foreign Minister Hossein Amir-Abdollahian said it hit militants in "missile and drone" strikes, saying no Pakistani national was targeted. Pakistan has not confirmed the nature of the violation, or the location of the strikes.

Only "terrorists" were hit, the Iranian foreign minister said at Davos, Switzerland, where he was participating in the World Economic Forum, alleging that those targeted were linked to Israel.

Provincial officials in Pakistan said two children were killed and several others injured by missile strikes near the Iran border.

The violation was an unprovoked and blatant breach of Pakistan's sovereignty and was "unacceptable," the Pakistan foreign ministry spokeswoman, Mumtaz Zahra Baloch, said, adding that the country reserved "the right to respond to this illegal act."

FOLLOWS STRIKES IN IRAQ AND SYRIA
The strikes in Pakistan came a day after similar attacks carried out by Tehran inside other neighbours, Iraq and Syria. Baghdad recalled its ambassador from Tehran after Iran's state-backed media said it had hit an Israeli espionage centre.

Jaish Al Adl has previously mounted attacks on Iranian security forces in the border area with Pakistan.

Pakistan will not allow Iran's ambassador, who was visiting his home country, to return, the ministry's spokesperson said in a statement.

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-e-Sabaz which is around 50 km inside Pakistan soil," a senior official of the Panjgur administration told Reuters.
"A mosque and three houses were damaged in the attack," another official said, adding that two young girls were killed and three other people injured.

China, close partners of Iran and Pakistan, urged restraint, with foreign ministry spokeswoman Mao Ning saying both should "avoid actions that would lead to an escalation of tension."

Hours before the strike, Pakistan's caretaker Prime Minister Anwarr-ul Haq Kakar had met Iranian Foreign Minister Hossein on the sidelines of the World Economic Forum in Davos, Switzerland.

"This violation of Pakistan's sovereignty is completely unacceptable and can have serious consequences," Pakistan's foreign ministry said in a statement.

It said the strike caused the "death of two innocent children while injuring three girls."
