ANKARA (Reuters) - Turkey is continuing discussions on how to observe and monitor a ceasefire between Azerbaijan and Armenia in the Nagorno-Karabakh region, Foreign Minister Mevlut Cavusoglu said on Tuesday, after the warring sides signed a Russia-brokered deal to end fighting. Under the deal, Russian peacekeepers will be deployed along the frontline in Nagorno-Karabakh and the corridor between the region and Armenia. Azeri President Ilham Aliyev said Turkey will also take part in the peace-keeping process. Speaking at a news conference in Ankara, Cavusoglu said the deal would ensure the seven regions around Karabakh are handed to Azerbaijan, adding that Turkey would continue to stand with its Azeri allies.
