The second deadly attack on a bus since February on the road between the old royal capital Luang Prabang and the town of Vang Vieng occurred recently. No foreigners were believed killed in this attack, but at least ten Laos died. Diplomatic sources believe the attacks were carried out by a Hmong rebel group that has been waging a low-level insurgency for the past 30 years. These attacks on buses traveling a popular tourist route may be an effort to disrupt the flow of tourist money to the government and to attract international attention to their cause.
