A series of explosions targeting public buildings in a small city in southern China have killed at least six people and injured dozens more.
The official Xinhua News Agency said there were 15 blasts in Liucheng county in the southern region of Guangxi and that six people were killed.
The city government of Liuzhou, which oversees Liucheng, said the explosions also injured 13 people, although later reports by state media said dozens were injured.
The blasts hit a hospital, local markets, a shopping centre, a bus station and several government buildings - including a jail and a township office building, according to a police statement posted by the local newspaper Nanguo Zaobao.
Liuzhou's police chief said the blasts were triggered by explosive devices delivered in several mail packages, state broadcaster CCTV reported.
The police chief said the case was under investigation. He did not name any suspects or offer any motive for the explosions.
Photos posted online showed smoke in local streets, strewn debris, dust clouds in the sky and the collapse of a five-story building.
