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.
Vjeruje se kako Al-Qaeda stoji iza nekoliko napada visokog profila u Istanbulu, uključujući četiri napada kamionima bombama u studenom 2003. godine, koji su za metu imali britanski konzulat, tursko sjedište HSBC banke i dvije sinagoge, a u kojima je poginulo 57 osoba, dok su stotine ranjene.
