Another possible instance of Hekmatyar's treachery toward his rivals occurred in 1987. The Paris-based group Médecins Sans Frontières reported that Hekmatyar's guerrillas hijacked a 96-horse caravan bringing aid into northern Afghanistan in 1987, stealing a year's supply of medicine and cash that was to be distributed to villagers. This would have allowed the villagers to buy food. French relief officials also asserted that Thierry Niquet, an aid coordinator bringing cash to Afghan villagers, was killed by one of Hekmatyar's commanders in 1986. It is thought that two American journalists traveling with Hekmatyar in 1987, Lee Shapiro and Jim Lindelof, were killed not by the Soviets, as Hekmatyar's men claimed, but during a firefight initiated by Hekmatyar's forces against another mujahideen group. In addition, there were frequent reports throughout the war of Hekmatyar's commanders negotiating and dealing with pro-Communist local militias in northern Afghanistan.
