Two Germans have been missing in Iraq for almost a week, German Foreign Minister Frank-Walter Steinmeier confirmed Monday.

"We cannot rule out that it was a kidnapping by force," he told reporters at an EU meeting in Brussels.

Steinmeier said the two had been missing since Feb. 6. He declined to give further details.

The Berliner Morgenpost newspaper reported in its Monday editions that the two apparently were kidnapped in Baghdad some days ago.

Three Germans previously taken hostage in Iraq were released unharmed.

Last May, two German engineers were freed after 99 days in captivity in Iraq. Another German was released after three weeks in December 2005.
