Beijing (CNN) -- Three explosions hit different government targets within a half an hour Thursday morning in eastern China, killing two people and injuring six others, local officials told CNN.
"A car bomb went off at 9:18 a.m. in the parking lot of the Fuzhou city prosecutor's office, followed by a blast at 9:20 a.m. at the Linchuan district government building and another car bomb at 9:45 a.m. near the local drug administration building," said Zhang Baoyun, a spokesman for the government of Jiangxi province, where Fuzhou is located.
One body was found in the district government building and another person died in the hospital, Zhang added.
Photos from the scene show large crowds gathering near one of the blast sites with a thick plume of black smoke in the air.
State-run Xinhua news agency quoted eyewitnesses as saying glass windows were shattered at the eight-story prosecutor's office building, while ambulances rushed in and out of the district government compound.
Authorities are still investigating the cause, while the injured -- including three in serious condition -- are at local hospitals, Zhang said.
He declined to confirm an earlier Xinhua report that blamed a disgruntled local peasant farmer for setting off the bombs because of an ongoing lawsuit.
Fuzhou is a city of nearly 4 million residents some 1,600 kilometers (975 miles) south of Beijing.
Last September the clashes between residents and officials in Yihuang, a county in Fuzhou, gained national attention.
Three residents doused themselves with gasoline and burned themselves to protest the forced demolition of their home by the local government.
One died in the hospital, prompting widespread outrage that eventually forced provincial authorities to sack several local officials.
