The White House on April 24, 2008 broke its official silence on the mysterious September 6, 2007 Israeli air strike. "We are convinced, based on a variety of information, that North Korea assisted Syria's covert nuclear activities," White House spokeswoman Dana Perino said in a statement. The statement came after intelligence officials briefed U.S. lawmakers about the Syrian nuclear facility that was destroyed by Israel last year. REUTERS/U.S. Government/Handout (UNITED STATES).
