Lawyers for a group of terrorist attack victims tried to convince a Brooklyn jury Thursday that a Jordan-based bank knowingly facilitated transactions used to finance 24 attacks carried out by Hamas, the Palestinian terrorist group, between 2000 and 2004.

It was the first day of a trial a decade in the making. The civil case is the first time a U.S. jury will hear claims that a bank financed terrorism. The United States designated Hamas as a terrorist group in 1997.
