Blast hits China tax office in apparent attack
Friday afternoon's explosion occurred at a district tax office in Changsha, capital of Hunan province, Xinhua said.
Initial investigations showed the explosion was a planned attack, Xinhua cited the city's police department as saying in a statement.
China is struggling to contain social tensions, and anger over issues ranging from the cost of health care to a rapidly widening rich-poor gap in the past has exploded into violence.
