Turkey has given the all clear for an Armenian plane to continue on its journey to the Syrian city of Aleppo after ordering it to land in eastern Turkey so its cargo of humanitarian aid could be searched, Deputy Prime Minister Bulent Arinc said.

Ankara has stepped up efforts to prevent its air space being used to supply the Syrian military and forced down a Syrian airliner travelling from Moscow last week, saying it was carrying Russian munitions destined for Syrian President Bashar al-Assad's military. (Reuters)
