The long-awaited trial for four Hamas terrorists suspected of plotting attacks against high-profile targets across Germany has finally begun.

“For the first time in Germany, people are facing charges of participating as members of the foreign terrorist organization Hamas,” said prosecutor Jochen Weingarten at the start of the proceedings on Tuesday.

Lebanese-born citizens, Ibrahim El-R, Abdelhamid Al A., along with Egyptian Mohamed B., and Dutch citizen Nazih R. spent years establishing and maintaining weapons caches across multiple countries.
