After the fall of Mohammad Najibullah's government in April 1992, different mujahideen factions entered the city and formed a government under the Peshawar Accords, but Gulbuddin Hekmatyar's party refused to sign the accords and started shelling the city for power, which soon escalated into a full-scale conflict. This marked the start of a dark period of the city: at least 30,000 civilians were killed in a period known locally as the "Kabul Wars." About 80 percent of the city was devastated and destroyed by 1996. The old city and western areas were among the worst-hit. A "The New York Times" analyst said in 1996 that the city was more devastated than Sarajevo, which was similarly damaged during the Bosnian War at the time.
