Daniel Pearl
Daniel Pearl was an American journalist who worked for The Wall Street Journal. On January 23, 2002, he was kidnapped by jihadist militants while he was on his way to what he had expected would be an interview with Pakistani Islamic scholar Mubarak Ali Gilani in Karachi, Sindh. Pearl had moved to Mumbai, India, upon taking up a regional posting by his newspaper and later entered Pakistan to cover the war on terror, which was launched by the United States in response to the September 11 attacks in 2001. At the time of his abduction, he had been investigating the alleged links between British citizen Richard Reid and al-Qaeda; Reid had reportedly completed his training at a facility owned by Gilani, who had been accused by the United States of being affiliated with the Pakistani terrorist organization Jamaat ul-Fuqra.
