Germany: Poison terrorist attack thwarted. Tunisian Muslim terrorist arrested in Cologne

German authorities have thwarted a plot by a Tunisian Muslim terrorist who created the deadly toxin ricin using castor bean seeds and planned to use the poison in an Islamic terrorist attack in Germany, federal prosecutors said Thursday.

Sief Allah H., whose last name wasn’t given in line with German privacy laws, was taken into custody Tuesday during a raid on his apartment in Cologne. The 29-year-old terrorist was formally arrested Wednesday after a judge reviewed the evidence.

Authorities are still investigating exactly how the Muslim terrorist planned to use the toxin, but said he was working on a “biological weapon” attack in Germany.

The terrorist is believed to have begun procuring material online in mid-May, prosecutors said. He succeeded in creating the toxin this month and investigators found it in the apartment search.

The seeds of the castor bean plant are naturally poisonous and can be used to create ricin. The substance kills the body’s cells by preventing them from creating protein. A few milligrams are enough to kill an adult if it’s eaten, injected or inhaled. Early symptoms include chest pain, breathing difficulties and coughing.

The terrorist is not known to have been a member of a terrorist organization but did have contacts with terrorists.

The Bild newspaper reported that American intelligence tipped off German investigators after they detected the terrorist’s online activity buying the seeds to make ricin.

The terrorist lived in the Chorweiler neighborhood of Cologne with his wife, a convert to Islam, and four children.

His wife was initially taken into custody but was later released, prosecutors said.
