Rebels Attack Prison Convoy in Myanmar Ethnic rebels in northern Myanmar staged a deadly attack on a prison convoy, state news media reported Friday, highlighting one of the country's violence-plagued corners days before President Obama's historic visit. About 30 ethnic Kachin rebels ambushed the five-car convoy on Wednesday in Kachin state, killing 2 convicts and injuring 14 others, the state-owned Kyemon newspaper reported. The newspaper did not give further details. Though President Thein Sein's government has concluded cease-fires with several ethnic guerrilla groups, it still faces a bitter insurgency from the Kachin Independence Army. Clashes between the military and ethnic rebels have displaced tens of thousands of civilians. Mr. Obama will visit Myanmar on Monday, in a first for a sitting president.
