<human>: At the age of 18, Khattab left Saudi Arabia to participate in the fight against the Soviet Union during the Soviet invasion of Afghanistan. During this time, he permanently incapacitated his right hand and lost several fingers after an accident with improvised explosives. The injury was treated with honey by Khattab on himself.  Khattab, while leader of Islamic International Brigade, publicly admitted that he spent the period between 1989 and 1994 in Afghanistan and that he had met Osama Bin Laden. In March 1994, Khattab arrived in Afghanistan and toured fighter training camps in Khost province. He returned to Afghanistan with the first group of Chechen militants in May 1994. Khattab underwent training in Afghanistan and had close connections with al-Qaeda. Several hundred Chechens eventually trained in al-Qaeda camps in Afghanistan.  Armenian sources claim that in 1992 he was one of many Chechen volunteers who aided Azerbaijan in the embattled region of Nagorno-Karabakh, where he allegedly met Shamil Basayev. However, the Azerbaijani Ministry of Defense denied any involvement by Khattab in the Nagorno-Karabakh war.  From 1993 to 1995, Khattab left to fight alongside Islamic opposition in the Tajikistan Civil War. Before leaving for Tajikistan in 1994, al-Khattab gave Abdulkareem Khadr a pet rabbit of his own, which was promptly named Khattab.  In an interview, Khattab once mentioned he had also been involved in the War in Bosnia and Herzegovina. The fragment of this interview in which he makes this statement can be found in the 2004 BBC documentary The Smell of Paradise, though he did not specify his exact role or the duration of his presence there.
