Pakistan inherited the Durand Line agreement after its independence in 1947, but the Afghan Government has always refused to accept the Durand Line Agreement. Afghanistan has several times tried to seize Pakistan's western provinces of Balochistan and Khyber Pakhtunkhwa. The then Afghan Prime Minister, Muhammad Hashim, said "if an independent Pashtunistan cannot be set up, the frontier province should join Afghanistan. Our neighbor Pakistan will realize that our country, with its population and trade, needs an outlet to the sea, which is very essential", in an interview with the Statesman. In 1949, Pakistan Air Force bombed the Afghan sponsored militant camps in border areas including an Afghan village to curb an unrest led by Ipi Faqir propagating independent Pashtunistan. Border clashes were reported in 1949–50 for the first time. On 30 September 1950, Pakistan claimed that Afghan troops and tribesmen had crossed into Pakistan's Balochistan, but the low-scale invasion was repelled after six days of fighting. The Afghan government denied its involvement and claimed that they were pro-Pashtunistan Pashtun tribesmen.
