Ankara is working on potential steps in response to the German parliament passing a resolution declaring the 1915 massacre of Armenians by Ottoman forces a genocide, Turkish deputy Prime Minister Nurettin Canikli said on Monday. 'It is not possible for us to remain indifferent to this,' Canikli told a press conference during a cabinet meeting. 'Work on whether it would be possible to overturn this decision and what steps can be taken is still underway,' he said.
