The International Maritime Bureau (IMB) maintains statistics regarding pirate attacks dating back to 1995. Their records indicate hostage-taking overwhelmingly dominates the types of violence against seafarers. For example, in 2006, there were 239 attacks, 77 crew members were kidnapped and 188 taken hostage but only 15 of the pirate attacks resulted in murder. In 2007 the attacks rose by 10 percent to 263 attacks. There was a 35 percent increase on reported attacks involving guns. Crew members that were injured numbered 64 compared to just 17 in 2006. That number does not include instances of hostage taking and kidnapping where the victims were not injured.
