Turkish President Abdullah Gul said on Saturday it was not possible to ignore the fact that Syria had shot down a Turkish fighter jet and said everything that needed to be done following the incident would be done, Turkish media reported.
"It is not possible to cover over a thing like this, whatever is necessary will no doubt be done," Gul told reporters from the central Anatolian city of Kayseri.
The Turkish military said it had lost contact with one of its F-4 fighter jets off the southern Turkish coast near Syria on Friday morning and Damascus later acknowledged it had shot the plane down.
