A leading al-Qaeda trainer and explosives expert involved in a range of European terrorist networks has been killed in Pakistan in a missile strike by US-led forces in Afghanistan, a media report said . Abu Suleman al-Jazairi, an experienced Algerian militant, was killed in the last few days, 'The Observer' reported quoting intelligence sources in Pakistan and Western Europe. 45-year-old al Jazairi, considered director of external operations for al-Qaeda, died along with at least 15 others when the house in which he was staying in Pakistan's Bajaur tribal district was hit by a missile fired from a Predator, an American pilotless drone. The house targeted and destroyed by the drone is believed to belong to a former Afghan Taliban defence minister, Maulvi Obaidullah, members of whose family, including women and children, are thought to have died. The surrounding areas are in the hands of militants linked to the Pakistan Taliban militant group blamed for the killing of former premier Benazir Bhutto last year. According to CIA chief Michael Hayden, "the ability to kill and capture key members of al-Qaeda continues, and keeps them off balance - even in their best safe haven along the Afghanistan-Pakistan border."
