A suicide bomber detonated a device in a government office in rural Anhui province yesterday morning, killing a village leader and injuring three officials, local media said.
The suspected bomber, identified as 51-year-old Wu Yongsheng, was killed instantly, while the 43-year-old head of Jindu village committee died later in hospital, the Xinan Evening News reported. Wu had the explosives strapped to his body, the report said.
Wu allegedly barged into a conference room where village officials were meeting at about 10am, according to the report.
A local villager was quoted as saying the village committee had repeatedly denied Wu a minimum subsistence allowance, a form of welfare.
An official from Zongyang county government refused to comment on a motive for the attack, but the report cited the Zongyang government information office as saying it was triggered by "private disputes".
A statement on the county government's website confirmed the number of casualties and said the case was under investigation.
The attack follows a series of bombings motivated by social grievances.
Attacks have been attributed to people who turn to violence out of frustration with local governments that fail to adequately address their petitions.
In November, a man set off a series of bombs outside Shanxi provincial party headquarters in Taiyuan , killing one and wounding eight others. Police said Feng Zhijun, 42, planted the bombs after his petitions failed to stop his home being demolished. He was sentenced to death last month, the South China Morning Post reported.
Meanwhile, a man from Yibin , Sichuan set a city bus ablaze during evening rush hour on Tuesday, killing himself and injuring 77 others.
