A man who murdered eight children outside their primary school last month was executed Wednesday in east China's Fujian Province.

Zheng Minsheng, 42, was shot in Nanping City after the death sentence had been approved by the Supreme People's Court (SPC).

The SPC reviewed Zheng's case and ratified the sentence handed down by the local court, said a statement released by the Intermediate People's Court of Nanping City.

Zheng, a former community doctor, stabbed eight children to death and seriously injured five others March 23 at the gate of the Nanping Experimental Elementary School.

An investigation found Zheng was acting in frustration at failures in his romantic life, said the statement.

Zheng was convicted of murder April 8 at the Intermediate People's Court of Nanping City. He appealed the sentence and asked for leniency, but this was rejected by the Fujian Provincial Higher People's Court April 20.?
