NATO offered political support for Turkey's campaign against militants in Syria and Iraq at an emergency meeting on Tuesday, and President Tayyip Erdogan signalled the alliance may have a "duty" to become more involved, Reuters reported. Turkey requested urgent consultations with its 27 NATO allies in Brussels after stepping up its role in the U.S.-led fight against ISIS with air strikes, also hitting Kurdistan Workers Party (PKK) camps in Iraq at the weekend. "We stand in strong solidarity with our ally Turkey," NATO Secretary General Jens Stoltenberg told alliance ambassadors at the start of a meeting he called right and timely "to address instability on Turkey's doorstep and on NATO's border".
