A blast damaged a residential building in southern China a day after 17 mail bombs killed seven and wounded more than 50. Chinese authorities have ruled out terrorism, according to state media.
The explosion caused damage to a six-story residential building in Liucheng, a county of the Guangxi region, early on Thursday, the official Xinhua news agency reported.
No injuries or deaths were immediately reported.
Thursday also marks China's national day, the start of a week-long holiday during which many government offices and businesses close.
The blast comesa day after 17 letter bombs killed seven people and wounded more that 50
in Liucheng county. The bombs targeted a hospital, market, shopping mall, a bus station and government offices, including a prison.
Authorities said they have identified a 33-year-old suspect, but have not suggested a motive. On Wednesday, police said they were treating the blasts as a "criminal act" and not an act of terrorism.
Small bombs are sometimes used by disgruntled citizens seeking to draw attention in what local media refer to as revenge attacks.
