Turkish President Recep Tayyip Erdogan says he will discuss buying US-made missiles with President Donald Trump this month.

Erdogans's comments come after Ankara's purchase of Russian missile system in July irked Washington and raised the prospect of US sanctions being rolled out against its NATO ally.

Meanwhile, U.S. State Department has said an offer to sell Raytheon's Patriot missile defence system to Ankara had expired.
