Al-Qaeda is believed to have been behind several high-profile attacks in Istanbul, including four truck bombs in November 2003, targeting the British Consulate, the Turkish headquarters of HSBC bank and two synagogues, killing 57 people and wounding hundreds.
Veruje se da Al Kaida stoji iza nekoliko velikih napada u Istanbulu, uključujuči četiri napada kamionima bombama u novembru 2003. godine, na čijoj meti su bili britanski konzulat, sedište HSBC banke u Turskoj i dve sinagoge, a u kojima je poginulo 57 osoba, dok je više stotina ranjeno.
