The UN office in Iraq says three foreigners have been killed and 14 wounded in a rocket attack against a UN compound in Baghdad. The United Nations says the victims were working for a catering company that provides services for the UN. Their nationalities have not been released. A UN official says the missile fell Saturday near a UN compound in the US-protected Green Zone. The official spoke on condition of anonymity for releasing the information ahead of a formal announcement. The UN presence in Iraq has been limited since the organization's Baghdad headquarters was bombed on Aug. 19, 2003, killing 22 people.
