Turkish President Abdullah Gul said on Saturday it was not possible to ignore 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. Gul said it was routine for jets traveling at high speed to cross borders for a short distance and an investigation will take place to determine if the plane was downed in Turkish airspace. The Syrian military said it shot down the Turkish F-4 air force jet that disappeared over the Mediterranean Friday, Reuters reported. "Our air defenses confronted a target that penetrated our air space over our territorial waters pre-afternoon on Friday and shot it down," a military statement said, according to Reuters. Search and rescue teams continue to look for the two pilots who were on board.
