Turkey’s Prime Minister Recep Tayyip Erdogan claimed on Sunday that Turkish armed forces had shot down the Syrian jet after it crossed the border into Turkey.
He warned of a heavy response if Syria violates Turkey’s airspace again.
However, Syrian officials on Sunday rejected Turkey’s claim about the violation of its airspace and said the plane was inside the Syrian airspace when it was downed. A Syrian army spokesman described the act as "a flagrant aggression."
Syrian officials say the warplane was targeting foreign-backed militants in the coastal province of Latakia, close to the border with Turkey.
Heavy clashes have recently broken out between the Syrian army and militants around Kassab, a border crossing with Turkey close to the Mediterranean.
