The Dutch government has agreed to sell up to 60 aging jet fighters to Turkey, the Defense Ministry said Friday.

From 50 to 60 of the Northrop NF-5 jets will be sold to Turkey after the Dutch air force retires them from service in the next five years, said ministry spokesman Cent van Vliet.The price and quantity still are being discussed, Van Vliet said. He said Dutch Deputy Defense Minister Jan van Houwelingen agreed to the sale during a visit to Turkey last week.

The single-engine jets, built in the 1960s, are being replaced by U.S.-built F-16 fighters.

Talks also were under way for the sale of 20 to 30 of the NF-5 jets to Greece, which frequently is at odds with Turkey over oil drilling rights in the Aegean Sea.
