BAGHDAD, Iraq – An influential Sunni clerical group called Wednesday for the release of five Westerners taken hostage in a grim revival of the kidnappings that shook Iraq last year, saying they should be freed on humanitarian grounds. The Association of Muslim Scholars is believed to have contacts with some Sunni insurgent groups and has helped mediate the releases of other captives in Iraq. The five include four aid workers from the group Christian Peacemaker Teams – Tom Fox, 54, of Clearbrook, Va.; Norman Kember, 74, of London; and James Loney, 41, and Harmeet Singh Sooden, 32, of Canada – and German archaeologist Susanne Osthoff, 43. The association said freeing Osthoff would recognize Germany’s “positive” stand toward Iraq. Germany strongly opposed the U.S.-led invasion in 2003.

In the northern city of Mosul, the head of the regional antiquities department, Muzahem Mahmoud al-Zawbai, said he warned authorities Osthoff was not safe and that he could not be responsible for her security due to insurgent activity. It was unclear if the authorities relayed the warning to Osthoff, who was working to renovate a historic house. 160Want local news?Sign up for the Localist and stay informed Something went wrong.
