A foreign ministry spokesman in Germany said Tuesday that his country was continuing to work for the release of a German hostage, hours after an insurgent group in Iraq posted a video showing the man who has been held for over six months. The video, posted late Monday, showed Sinan Krause seated drinking tea in front of a blue backdrop and talking with his mother, Hannelore, who was freed in July and weeped openly in the footage. As the image shifted to Hannelore sitting alone dressed in her headscarf, a voice was heard saying she was released because she converted to Islam. Germany's Foreign Ministry spokesman Martin Jaeger said the recording was clearly old. He stressed that the ministry's crisis unit "is continuing to work with all vigor for the release of the hostage."
