Turkey's foreign minister has said the fighter jet shot down by Syrian air defence forces on Friday was in international airspace when it was hit.
Ahmet Davutoglu said the unarmed plane was not on a secret mission related to Syria, but had mistakenly entered Syrian airspace before the incident.
Syria maintains that it engaged the aircraft in its airspace "according to the laws that govern such situations".
The Turkish and Syrian navies are still searching for the two crew members.
Turkish Prime Minister Recep Tayyip Erdogan is meeting the leaders of the three other parties in parliament to discuss how to respond.
Turkey had also called a meeting of Nato member states on Tuesday.
