Militant Islamic groups have flexed their muscles over the past few years. Some have been accused of having links with Osama Bin Laden’s al-Qaeda organisation, including the group blamed for the 2002 Bali bombings, which killed 202 people. Lying near the intersection of shifting tectonic plates, Indonesia is prone to earthquakes and volcanic eruptions. A powerful undersea quake in late 2004 sent massive waves crashing into coastal areas of Sumatra, and into coastal communities across and East Asia. The disaster left more than 220,000 Indonesia dead or missing.
