A total of four German citizens are among a group of women who were captured by Iraqi forces in the Iraqi city of Mosul last week, a foreign ministry source said on Tuesday.

The foreign ministry on Monday said that two women were among those seized, including a 16-year-old teenager, Linda Wenzel, who had run away from her home in the state of Saxony last year.

The source on Tuesday said that two others had now been confirmed as German citizens by consular officials who visited them.

German prosecutors on Monday said they were investigating the teenager on suspicion of membership in a foreign terrorist organization, alongside the three others.
