A US-born man pleaded guilty Tuesday to helping to train fellow Al-Qaeda agents to carry out bombings in Europe and the United States, after a five-year global investigation, officials said. The targets included European tourist resorts frequented by Americans, as well as US military bases, embassies and consular offices in Europe. "Today's guilty plea brings an end to the long, dangerous career of Christopher Paul, an Ohio native who joined Al-Qaeda in the early 1990s, fought in Afghanistan and Bosnia and conspired with others to target Americans both at home and abroad," said Acting Assistant US Attorney General Patrick Rowan. "His conviction demonstrates our continuing resolve to protect the American public against terrorism."
