A Turkish jet downed June 22 was flying in tandem with another aircraft when Syrian forces took it down, according to Republican People Party (CHP) deputy Orhan Düzgün.
Düzgün demanded that the government reveal the nationality of the accompanying jet, which "Hatay locals saw with their naked eyes."
"There were two planes flying. The fate of that second plane remains unknown. The government now denies the existence of a plane clearly seen by the people of Hatay," Düzgün said.
"The key to solving this issue is [the second jet]. Who did it belong to and what was it doing over there?" Düzgün asked.
The second jet belonged to a NATO
member but further information on its country of origin has not been provided by official sources, Düzgün said.
