A legal team is going to New York to prevent the use of evidence provided by Germany in seeking a death penalty. Berlin wants to ensure that promises made by the US are kept if the suspects are found guilty. 

A team of observers from the German government is going to New York to oversee the trial of five suspects accused of orchestrating the September 11 terrorist attacks in the United States, the news magazine Der Spiegel reported on Saturday.

The federal trial of the suspect Khalid Sheikh Mohammed and his four co-defendants was announced on November 13 by the US Justice Department. The government also asserted that it intends to seek the death penalty if the accused are found guilty.

Germany, which does not have a death penalty, provided evidence for the trial on the condition that it could not be used to support a death sentence. Several members of the al Qaeda cell that planned and executed the attacks of September 11 were previously based in the northern German city of Hamburg.
