A pair of accused hijackers have died following a foiled attempt to take control of a plane in China's Xinjiang region, state media says. Six Uighur men were arrested Friday in the incident, in which suspects wielding explosives used a crutch to pummel the cockpit door. Four crew members were hurt, but the 92-passenger plane turned back and landed safely. The hospitalized suspects died of injuries following a fight with the crew, state media says. But a German Uighur rights group rejects the hijacking story, saying the fight centered on a disagreement over seating, the AP reports.
