BERLIN — A German woman who was abducted in Iraq on February 6 was freed Tuesday, Foreign Minister Frank-Walter Steinmeier said. There was no news of the fate of her son, who was kidnapped at the same time.

The woman, Hannelore Krause, 61, “is in German care at our embassy in Baghdad,” Mr. Steinmeier said yesterday in Berlin in a statement aired on N24 television. “But as much as we are relieved about her release, there remains the pressing uncertainty about her son’s fate.”

Mr. Steinmeier said a Foreign Ministry crisis team will continue to “do everything” it can to help free the son, Sinan, 20. The minister declined to give further details about Tuesday’s release.

The mother and son were abducted outside their Baghdad home. Their kidnappers twice threatened in videos posted on the Internet to kill them unless Germany withdraws its military forces from Afghanistan. The first video was posted March 10 on a Web site used by groups linked to Al Qaeda in Iraq. As in the second video, almost a month later, masked kidnappers set a 10-day deadline. The ultimatums elapsed without incident. Germany’s 3,000 troops in northern Afghanistan are part of a North Atlantic Treaty Organization force working to stabilize the country under the leadership of President Karzai.

Three other Germans are known to have been kidnapped in Iraq in the past 21 months. Susanne Osthoff, an archeologist married to an Iraqi, was abducted for three weeks before being freed in December 2005. Rene Braeulich and Thomas Nitzschke were kidnapped early last year, a day after arriving in Iraq to carry out contract work. They were released after 99 days.
