Another explosion hit the Chinese city of Liuzhou on Thursday morning, just a day after a series of 17 blasts killed 7 people and wounded 50 others, state-run media reported.
XInhua did not report any casualties and it was not immediately known if the blast was related to Wednesday’s attacks which involved parcel bombs. The devices were reportedly sent to locations ranging from hospitals and shopping malls to prisons and government offices.
Thursday is the first day of the week-long National Day public holiday in China.
A 33-year old suspect — identified only by his last name Wei — is being hunted in connection with Wednesday's blasts, Guangxi Police said.
Xinhua reported that local police have ruled out terrorism and are treating the bombings as a criminal act.
The parcel service was temporarily suspended throughout the Liucheng county area which includes Liuzhou, according to state-run broadcaster CCTV.
Guangxi sits on the border with Vietnam and has several ethnic minorities, but is generally peaceful.
Disaffected or mentally unstable Chinese people have set off explosions in public places in the past. Explosives are relatively easy to come by, as they are widely used in China's large mining industry.
