Gunmen abducted the president of the Libyan Olympic Committee in the nation’s capital, grabbing him from his car and bundling him into a waiting vehicle, his brother said Monday. According to witnesses, the committee chief, Ahmed Nabil al-Taher al-Alam, was kidnapped on Sunday near the organization’s offices in Tripoli, said his brother, Salah al-Alam. Security officials said they were investigating but did not provide any details. The abduction comes amid a wave of score-settling after Libya’s eight-month civil war. Dozens of former rebel groups now operate independently, often ignoring the nation’s weak central authorities. Five Libyans have qualified to compete in the 2012 Summer Olympics.
