Bin Laden and al-Zawahiri organized an al-Qaeda congress on June 24, 1998. A week prior to the beginning of the conference, a group of well-armed assistants to al-Zawahiri had left by jeeps in the direction of Herat. Following the instructions of their patron, in the town of Koh-i-Doshakh, they met three unknown Slavic-looking men who had arrived from Russia via Iran. After their arrival in Kandahar, they split up. One of the Russians was directly escorted to al-Zawahiri and he did not participate in the conference. Western military intelligence succeeded in acquiring photographs of him, but he disappeared for six years. According to Axis Globe, in 2004, when Qatar and the U.S. investigated Russian embassy officials whom the United Arab Emirates had arrested in connection to the murder of Zelimkhan Yandarbiyev in Qatar, computer software precisely established that a man who had walked to the Russian embassy in Doha was the same one who visited al-Zawahiri prior to the Al-Qaida conference.
