One person was killed and eight injured in a series of explosions near a provincial office of the ruling Chinese Communist Party (CCP) in northern Taiyuan city, local media reported.
Several explosions were heard yesterday morning outside the party headquarters in the capital city of northern Shanxi province, two hours by train from Beijing.
The blasts came amid heightened security before a key CCP meeting in Beijing starting this Saturday, and a little over a week after a car crash at Beijing's Tiananmen Square killed five and injured 40 people. The authorities have labelled the Oct 28 incident as a "terror attack" and blamed it on Muslim Uighurs from western Xinjiang region.
In the Shanxi incident, some of the devices were placed in a garden near the Shanxi party headquarters. They exploded around 7.40am yesterday, shattering the windows of nearby vehicles, state news agency Xinhua reported.
One of the eight hurt suffered critical injuries, it noted.
Shanxi police confirmed on its official microblog that a series of small devices were set off near the party headquarters. "Party and city leaders rushed down immediately to deal with it and the police are doing all they can to solve the case," they said.
Xinhua said the explosive devices might be homemade, going by the ball bearings and circuit boards found after the blasts.
Eyewitnesses Liu Guoliang and Zheng Quan told Xinhua that they were driving near the party building when they heard an explosion and saw smoke and sparks. They later heard another blast from a smoking minivan.
"Explosions sounded seven to eight times," a cleaner at the scene told the China News Agency. "What flew out from the blasts were nails and ball bearings."
Another man pointed to blood on the pavement and said that an old woman taking her grandchild to school was hit by flying debris from the blasts.
