BEIJING - A man who in 2009 killed six of his family, including his own children, was executed Friday in Beijing.

Li Lei, 31 years old, stabbed his parents, two sons, wife and sister to death on November 23, 2009, at their home in Beijing's Daxing District. Li's sons were aged one and six-years old.

Li was sentenced to death by the Beijing No. 1 Intermediate People's Court last October, and was ordered to pay 3.45 million yuan (540,000 US dollars) in compensation to his grandmothers and parents-in-law.

Li did not appeal the criminal part of the ruling, but appealed to lower the compensation amount.

In March, the Beijing Higher People's Court upheld the verdict.

The death penalty was approved by the Supreme People's Court.

Li told police after being nabbed that he had been annoyed by his family, including his parents, sister and wife, who expected too much from him.
