Tensions are also on the rise with Syria’s neighbor, Turkey, following Syria’s downing of a Turkish fighter jet. On Tuesday, Turkish Prime Minister Tayyip Erdogan acknowledged the plane had briefly violated Syrian airspace but called the shooting “a hostile and heinous attack.” Turkey says the plane entered Syrian airspace by mistake, but there has been speculation it may have been on a spying mission. In Brussels, NATO Secretary General Anders Fogh Rasmussen said the alliance fully supports Turkey in its standoff with Syria.

Anders Fogh Rasmussen: “We consider this act to be unacceptable and condemn it in the strongest terms. It is another example of the Syrian authorities’ disregard for international norms, peace and security and human life.”
