The Foreign Ministry said Thursday that the bodies of the two South Koreans killed in Sunday's insurgent attack in Iraq arrived in Baghdad Wednesday afternoon local time.

Officials said that they will be transferred again to a U.S. military base in Kuwait soon before being flown home aboard a civilian flight around this weekend.

Suspected Iraqi insurgents shot to death 61-year-old Kwak Kyung-hae and 46-year-old Kim Man-soo in an ambush on a highway near Tikrit, the hometown of former Iraqi President Saddam Hussein.

Two other South Korean workers were wounded in the attack.

The injured, who are recovering at a U.S. military hospital in Iraq, were scheduled to leave for Germany aboard a U.S. military plane for further treatment, but their departure is reportedly being delayed for unknown reasons.
