China said Wednesday it had summoned Israel's ambassador in Beijing and demanded an apology over an Israeli air strike in Lebanon that killed a Chinese United Nations worker.

Foreign ministry spokesman Liu Jianchao said Chinese assistant foreign minister Zhai Jun had called in Israeli ambassador Yehoyada Haim on Wednesday morning for an "emergency" meeting over Tuesday's incident.

"The Chinese side… demands that the Israeli side open a comprehensive investigation, apologize to the Chinese side and the victim's family and help the Chinese side in carrying out the mourning activities," Haim was told, according to Liu.
