Zia lifted martial law in 1985, holding party-less elections and handpicking Muhammad Khan Junejo to be the Prime Minister of Pakistan, who in turn reappointed Zia as Chief of Army Staff until 1990. Junejo however gradually fell out with Zia as his political and administrative independence grew – such as by asking his Minister of State to sign the Geneva Accord, which President Zia disliked. After a large-scale explosion at a munitions store in Ojhri, Junejo vowed to bring those responsible for the significant damage caused to justice, implicating several times the Inter-Services Intelligence (ISI) Director-General Akhtar Abdur Rahman.
