From BBC News:
Iran has admitted carrying out a missile and drone attack on western Pakistan on Tuesday.
Officials in Islamabad said two children were killed and three others injured in the attack in Balochistan.
Iran's foreign minister said the operation targeted the militant group Jaish al-Adli, which he described as an "Iranian terrorist group" in Pakistan.
As a result the Pakistan's government recalled its ambassador to Iran and has blocked Tehran's envoy from returning.
The Balochistan attack comes after Iran attacked targets in Iraq and Syria earlier this week.
