The US should do what is necessary on F-16 sales to complete the process for Sweden's NATO bid, Turkish President Recep Tayyip Erdogan said on Friday, Paralel.Az reports citing Anadolu Agency.

"If we are two NATO allies, then you should do your part, simultaneously, our parliament will make a necessary decision," Erdogan told journalists on his return flight from a one-day visit to Greece.

"You say that you will take a step on the F-16 issue after it passes through Congress; I also have a parliament. It is not possible for me to take such a step before it passes through my parliament."

Erdogan signed Sweden's NATO accession protocol and submitted it to parliament on Oct. 23. On Nov. 16, parliament's Foreign Affairs Committee postponed consideration of the protocol.
