On Wednesday, 17 explosions took place in the province’s Liucheng county killing seven people. A suspect, believed to have sent the bombs via post, has been arrested.
Local media claimed that it was not clear whether Wednesday’s events are connected with the Thursday explosion, which took place in a residential building of six floors.
Earlier, a series of parcel bomb blasts have hit the city of Liucheng in the China's Guangxi province. At least seven people have been killed and 51 others injured.
Police have arrested a suspect in connection with the incident.
In recent weeks, China has been hit by multiple explosions. Last month, several blasts hit the country’s chemical plants and industrial warehouses, killing scores of people.
