HONG KONG — A man who was angry over a court ruling in the case of his daughter’s murder used his car to run down a group of high school students in northern China, causing 13 to be hospitalized with injuries, the state news media reported on Tuesday. It was the second major attack on students in China in less than two weeks. The man, Yin Tiejun, 48, ran down 23 students at the school in Fengning County, in Hebei Province, during their lunch break on Monday, Xinhua, the state news agency, reported. He then tried to set fire to his car by igniting a container of diesel fuel. Xinhua quoted the police as saying he was upset that the court did not sentence all his daughter’s killers to death. Mr. Yin has been detained on charges of endangering public safety. As with the previous attack, in which a man with a meat cleaver injured 23 students in adjacent Henan Province on Dec. 14, the episode received limited attention from the state news media. The Chinese media have given heavy coverage instead to the school shooting in Newtown, Conn. — in which 20 first graders and 6 adults were killed by a gunman who had already killed his mother and later killed himself — and the shootings on Monday of four firefighters, two of whom died, in Webster, N.Y.
