UPDATE 1-Turkey's Erdogan says S-400 systems will be delivered within 10 days -NTV

Turkish President Tayyip Erdogan said the first delivery of the Russian S-400 missile defence system would take place within 10 days, broadcaster NTV reported on Sunday, a day after he said there would be no U.S. sanctions over the deal. Turkey and the United States, NATO allies, have been at odds over Ankara's decision to purchase the S-400s, with Washington warning of U.S. sanctions if the delivery took place. Turkey has dismissed the warnings, saying it would not back down.
