Seven years on, Osama bin Laden still at large

Osama bin Laden remains elusive despite a $25 million reward by the USAF. The US-led coalition has deployed thousands of troops and agents in Afghanistan and Pakistan, yet Bin Laden's whereabouts are unknown. His last video appearance was over a year ago, leading to speculation about his health. Some believe he avoids media to hide his weakened state. The difficult Afghan terrain and high human cost hinder his capture. Bin Laden is protected by hundreds of armed men. Recent arrests and documents suggest he is alive and possibly planning new attacks.
