Terrorism in Southeast Asia - Part II NPR's Michael Sullivan has the second of a five-part series on terrorism in Southeast Asia. Al Qaeda's Southeast Asian operations may have begun in the Philippines, but neighboring Indonesia is the most populous Muslim country in the world and it has provided the most fertile ground for militant Islam. Several alleged terrorist groups have been active in Indonesia for years. One of them is the group called Jemaah Islamiyah. Jemaah Islamiyah is believed responsible for dozens of attacks in Indonesia in the past several years including the bombings on the resort island of Bali in October. And investigators say it's clear the group has close ties to Osama bin Laden's al Qaeda network.
