Here are some facts on the group Pakistan targeted and the restive province at the heart of the tension.
WHICH GROUP DID PAKISTAN TARGET IN IRAN?
The Baloch Liberation Front (BLF), which an intelligence official called the target of Pakistan's strikes in Iran, seeks independence for Pakistan's western province of Balochistan.
They also attack Chinese projects, and occasionally kill Chinese workers despite Pakistan's assurances that it is doing all it can to protect the Chinese projects.
It borders Iran's Sistan-Baluchestan province where Pakistan carried out its strikes.
