But one group, the Hezb-e Islami led by Gulbuddin Hekmatyar, presumably supported and directed by Pakistan's Inter-Services Intelligence (ISI), did not join the negotiations and announced its intent to conquer Kabul alone.
[5] The Peshawar Accord of 25 April 1992, which established a power-sharing interim government to take control of Kabul, was signed by six of the seven major Afghan anti-Soviet resistance parties[5] (notably excluding the Hezb-e Islami ["Islamic Party"] faction of Gulbuddin Hekmatyar, a Pashtun, who refused to sign the Accord), and supported by some remnants of the Najibullah administration.
[5] Making steady gains throughout 1995 and 1996, the Taliban were able to seize control of the capital city of Kabul in September 1996, driving the Rabbani government and other factions northward, and by the end of the year occupying two-thirds of Afghanistan.
[5] The ousted Rabbani government formed a political coalition with Tajik leader Ahmed Shah Massoud, Uzbek warlord Abdul Rashid Dostum, and the Shia Hizb-i-Wahdat faction (dominated by Hazaras) of Karim Khalili.
[5] Its formal name was United Islamic Front for the Salvation of Afghanistan, known in the Western world as the Northern Alliance, and its goal was to take back the country from the Taliban.
International pressure forced both sides to negotiate, but the demands posed by either party were so high that the differences were irreconcilable, and a political impasse ensued.
[5] The country was in a dire state according to a 1997 United Nations report, which found that the infant mortality rate was 25%, numerous civil casualties due to landmines, economic blockades imposed by the militias causing hunger, and international humanitarian organisations being unable to carry out their work.
Taking advantage of the resistance factions' disunity the Taliban launched a campaign, rapidly conquering the provincial capital cities of Maimana, Sheberghan, and finally Mazar-i-Sharif (8 August 1998).
