They are accused of seeking out and setting up weapons depots for the militant group across Europe so militants could later use the firearms and ammunition for attacks against Israeli and Jewish targets on the continent, prosecutors said when filing charges last year.
The weapons were allegedly moved around Europe in preparation for Hamas' Oct. 7, 2023, attack against Israel, prosecutors said.
Hamas also considered targeting the Israeli embassy in Berlin, the area around Tempelhof Airport in the capital and the U.S. Ramstein Air Base in Germany, authorities said.
The attack triggered Israel's air and ground offensive in Gaza, which has killed more than 48,200 Palestinians, according to Gaza's Health Ministry, which does not distinguish between combatants and civilians.
A trial began Tuesday in Germany for four alleged Hamas members suspected of organizing weapons caches across Europe.
