(ANSA-AFP) - KARLSRUHE, 15 LUG - Germany's highest court on Tuesday threw out a case brought by two Yemenis seeking to sue Berlin over the role of the US Ramstein airbase in a 2012 drone attack, ending a years-long legal saga. Plaintiffs Ahmed and Khalid bin Ali Jaber first brought their case to court in 2014 after losing members of their family in the strike on the village of Khashamir. The case has since been through several German courts. But the Constitutional Court on Tuesday ultimately ruled that Berlin is not required to take action against such attacks, which were not judged to be in breach of international law. Washington has for years launched drone strikes targeting suspected Al-Qaeda militants in Yemen, an impoverished country that has been torn by fierce fighting between its beleaguered Saudi-backed government and Iran-backed rebels. The two Yemeni men, supported by the Berlin-based European Center for Constitutional and Human Rights (ECCHR), had argued that Germany was partly responsible for the attack because the strike was aided by signals relayed via the Ramstein base in western Germany.
