Pakistan summons Tehran's top diplomat in Islamabad, accusing Iran of a territorial attack

Pakistan has summoned Iran's top diplomat in Islamabad over what it describes as an unprovoked violation of its airspace.

Tehran fired a missile that landed in Pakistan's Balochistan province - killing at least two children.

Iran says it was targeting the headquarters of the 'Jaish al-Adl group'.

It also blames them for several targeted attacks on security forces over the years.
