The Balochistan Liberation Army (BLA) has conducted a low-level separatist insurgency against the state for nearly two decades.
The organization, which grew out of anger over the state's perceived monopoly over the province's mineral resources, previously have killed and kidnapped Chinese engineers working in the province.
Balochistan, the country's largest but least populated province, is at the core of the massive multibillion-dollar cooperation deal known as China-Pakistan Economic Corridor (CPEC).
