ISTANBUL - Six German lawmakers will visit a key airbase in Turkey on Wednesday, a Turkish official told AFP, as the NATO allies seek to move on from a bitter diplomatic row. The German parliament in June joined more than 20 countries in recognising the Ottoman Empire's World War I-era massacre of Armenians as a genocide, prompting fury from Ankara. Turkey promptly banned German lawmakers from visiting the Incirlik base in southern Turkey, where Germany has around 240 troops as part of the international coalition fighting the Islamic State group across the border in Syria.
