Ibn al-Khattab

In an interview, Khattab once mentioned he had also been involved in the Bosnian War. 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.

The origins and real identity of Khattab remained a mystery to most until after his death, when his brother gave an interview to the press. He died on 20 March 2002 following exposure to a poisoned letter delivered via a courier who had been recruited by Russia's Federal Security Service.

Khattab was falsely reported dead when Guantanamo captive Omar Mohammed Ali Al Rammah faced the allegations that he witnessed Khattab being killed in an ambush in Duisi, a village in the Pankisi Gorge of Georgia on 28 April 2002.

Khattab later survived a heavy-calibre bullet wound to the stomach and a landmine explosion. He died of poisoning in early morning on 20 March 2002, when a Dagestani messenger hired by the Russian FSB gave Khattab a poisoned letter the day before. Chechen sources said that the letter was coated with "a fast-acting nerve agent, possibly sarin or a derivative". The messenger, a Dagestani double agent known as Ibragim Alauri, was turned by the FSB on his routine courier mission. Khattab would receive letters from his mother in Saudi Arabia, and the FSB found this to be the most opportune moment to kill Khattab. It was reported that the operation to recruit and turn Ibragim Alauri to work for the FSB and deliver the poisoned letter took some six months of preparation. Alauri was reportedly tracked down and killed a month later in Baku, Azerbaijan on Shamil Basayev's orders. Ibn Al-Khattab was succeeded by Emir Abu al-Walid.

During the course of the war in 2000, Khattab took over the leadership of Arab Mujahideen in Chechnya and participated in leading his militia against Russian forces in Chechnya, as well as managing the influx of foreign fighters and money (and, according to the Russian officials, also planning of attacks in Russia).

A Federal Security Service of the Russian Federation (FSB) investigation named Khattab as the mastermind behind the September 1999 Russian apartment bombings. However, on 14 September 1999, Khattab told the Russian Interfax news agency in Grozny that he had nothing to do with the Moscow explosions; he was quoted as saying, "We would not like to be akin to those who kill sleeping civilians with bombs and shells."

In 1998, along with Shamil Basayev, Khattab created or reorganized the Mazhlis ul Shura of the United Mujahids (Consultative Council of United Holy Warriors), the Congress of the Peoples of Dagestan and Ichkeniya, the Special Purpose Islamic Regiment (SPIR), the Islamic International Peacekeeping Brigade (IIPB) (also known as the Islamic Peacekeeping Army) and a group of female suicide bombers, the Riyadus-Salikhin Reconnaissance and Sabotage Battalion of Chechen Shahids. In August–September 1999, they led the IIPB's incursions into Dagestan, which resulted in the deaths of at least several hundred people and effectively started the Second Chechen War.

On 22 December 1997, over a year after the signing of the Khasav-Yurt treaty and the end of the first war in Chechnya, the Arab mujahideen and a group of Dagestani rebels raided the base of the 136th Armoured Brigade of the 58th Division of the Russian Army in Buinaksk, Dagestan.

According to Khattab's brother, he first heard about the Chechen conflict on an Afghan television channel in 1995; that same year, he entered Chechnya, posing as a television reporter. He was credited as being a pioneer in producing video footage of Chechen rebel combat operations in order to aid fundraising efforts as well as international recruitment, and he himself achieved notoriety in 1996 when he himself filmed an ambush he led against a Russian armored column in Shatoy. Not long after his arrival he married an ethnic Lak woman from Dagestan, the sister of Nadyr Khachiliev, an Islamist and leader of the Union of the Muslims of Russia, which has been seen as a way to already internationalize the Chechen struggle.

His units were credited with several devastating ambushes on Russian columns in the Chechen mountains. His first action was the October 1995 ambush of a Russian convoy which killed 47 soldiers. Khattab gained early fame and a great notoriety in Russia for his April 1996 ambush of a large armored column in a narrow gorge of Yaryshmardy, near Shatoy, which killed up to 100 soldiers and destroyed some two or three dozen vehicles. In another ambush, near Vedeno, at least 28 Russian troops were killed. .

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.

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.

Khattab, while the 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.

He was described as a brilliant student, scoring 94 percent in the secondary school examination, and initially wanted to continue his higher studies in the United States, even if he was already fond of Islamic periodicals and tapes as opposed to his siblings, to the extent they renamed him after the second caliph Umar ibn al-Khattab and he would retain the title during his militant activities, which began in 1987, at the age of 17, by joining the Afghan Arabs against the Soviet Union.

Samir Saleh Abdullah (Arabic: سامر صالح عبد الله ‎; 14 April 1969 – 20 March 2002), more commonly known as Ibn al-Khattab or Emir Khattab (also transliterated as Amir Khattab and Ameer Khattab, meaning Commander Khattab, or Leader Khattab), was a Saudi Arabian-born mujahid who participated in the First Chechen War and the Second Chechen War.
