The cause of the blast that occurred in Fuzhou, Jiangxi province, was being investigated, Xinhua news agency reported.

The bomb occurred less than 100 meters away in Fuzhou that shook the prosecutor's office, a district-level government office and the district food and drug administration, Xinhua reported. The windows of the prosecutor's office were devastated after the explosion, it added.

In past years, many mentally unstable or unhappy Chinese citizens have set off explosions near Jiangxi province, which is a home to many mines in China.

“Two cars exploded within a short time,” Jiangxi traffic radio said.

Earlier this month, a petrol bomb attack at a rural bank in a heavily Tibetan region by a disgruntled former employee wounded 49 people.
