Transportation - note:
the International Maritime Bureau (IMB) reports that 2011 saw a very slight (1%) decrease in global pirate activities with marginally fewer people taken hostage at sea; in 2011, pirates attacked a total of 439 ships world-wide including hijacking 45 ships, capturing 802 seafarers, and killing eight; while the Horn of Africa remains the most dangerous area for maritime shipping, accounting for more than 50% of all attacks in 2011, a number of attacks also occurred in the coastal waters of Indonesia, the South China Sea, Bangladesh, and West Africa; as of July 2012, there were 189 attacks worldwide with 20 hijackings; the Horn of Africa remains the most dangerous region in 2012 with 70 attacks, 13 hijackings, 212 hostages seized; as of July 2012, Somali pirates held 11 vessels and 174 hostages; the decrease in successful pirate attacks is due, in part, to more aggressive anti-piracy operations by international naval forces as well as the increased use of armed security teams aboard merchant ships
