The aid group Christian Peacemaker Teams has confirmed that four of its members were taken hostage Saturday.
German TV broadcast photos Tuesday showing a blindfolded German woman being led away by armed captors in Iraq. Six Iranian pilgrims, meanwhile, were abducted by gunmen north of Baghdad.
The pictures of Susanne Osthoff were taken from a video in which her captors demanded that Germany stop any dealings with Iraq's government, according to Germany's ARD television. Germany has ruled out sending troops to Iraq and opposed the U.S.-led war.
