Germany’s highest court has rejected a case brought by Yemeni plaintiffs who argued the German government failed in a duty to protect relatives who they say were killed in a 2012 drone strike against an attack controlled with help from a U.

Germany's top court has decided that the US air base in Ramstein may be used for lethal drone strikes, but Germany also has a duty to protect.

Berlin is not required to intervene in U.S. drone activities at the Ramstein air base in southwestern Germany, the country's top court ruled on Tuesday in dismissing a complaint brought by Yemeni nationals whose family members were killed in a strike.
