Liebig, a reporter for the German weekly magazine Focus, died in an Iraqi missile attack while accompanying the U.S. Army's 3rd Infantry Division south of the capital, Baghdad. Both Liebig and Julio Anguita Parrado, a Spanish journalist also killed in the incident, were embedded with the division, according to Agence France-Presse.
According to Focus editor-in-chief Helmut Markwort, the two men had decided not to travel with the unit to Baghdad, believing they would be safer at the base. Two U.S. soldiers were also killed during the attack, and 15 were injured.
Liebig, 35, had worked for Focus since 1999.
