Apart from its clashes with India over Kashmir, Pakistan has to deal with armed conflict with separatists in the province of Balochistan, close to the Iranian border.

Origin of the conflict
Ethnic leaders of the Baloch tribe argue there has been too little economic development in the region and they are isolated politically. This is why they wish to have more autonomy and independence in the region. This conflict is quite old, but in 2004 it gained momentum after claims of locals that major development projects in their region did not take local needs into account and a civil war ensued. Furthermore, Balochistan is one of the poorest regions of Pakistan, in spite of the presence of gas and minerals. Unequal distribution of its natural riches causes quite some dissent. Groups striving for more independence or autonomy sometimes resort to violent methods.    

Actors involved
This is not an international conflict, as all actors involved are in Pakistan. Warlords and fighters for independence are the separatists who fight the Pakistani government. They have attacked gas, electricity and railroad infrastructure. 

Chronological timeframe
When India and Pakistan became independent from Great Britain in 1947, the regions were allowed to choose whether they wished to adhere to Pakistan, India, or preferred independence. The province Kalat, led by Mir Ahmed Yar Khan, chose independence. The first war over this was fought in 1948, when the government sent troops to force its leader to give up the province. His brother continued a guerrilla war for independence against the Pakistani army. Four conflicts between civilians and army ensued; 1958-1959, 1963-1969, 1973-1977, the latest started in 2004 and is still going on.
