    The language used in a letter sent from the United States to Ankara regarding Turkey's removal from the F-35 fighter jet programme does not suit "the spirit of alliance", Turkish Defence Minister Hulusi Akar has said.

    US acting Secretary of Defence Patrick Shanahan's letter to his counterpart had outlined last week how Turkey would be pulled out of the multi-country F-35 fighter jet programme unless Ankara reconsidered its plans to purchase Russia's S-400 missile defence system as of July 31.

    Akar, cited by the defence ministry in a statement on Wednesday, also said Turkey was preparing a response to the letter and that it would be sent to the US in the coming days. He added that he would be speaking by phone with Shanahan on Thursday.

    Shanahan, quoted by Turkey's state-run Anadolu news agency, confirmed on Tuesday that he intended to discuss the spat with Ankara with his Turkish counterpart.

    Akar's statement comes a day after it was reported that Washington halted the training of Turkish F-35 pilots at an airbase in the US state of Arizona.

    The move came faster than expected, only days after Shanahan told Akar that Turkish pilots, who are already in the country, could remain until the end of July.

    US concerns

    The US says Turkey's missile defence acquisition from Russia poses a threat to Lockheed Martin's F-35 stealth fighters, which Ankara also wants to buy, adding that Turkey cannot have both.

    President Recep Tayyip Erdogan said many times it was "out of the question" for Turkey to back away from its deal with Moscow.

    On Tuesday, Russia said it planned to deliver the system to Turkey in July.

    The standoff threatens to bring US sanctions to Turkey, which would hurt the recession-hit economy, and raises questions over its role in the North Atlantic Treaty Organization (NATO).

    Strains in American-Turkish ties already extend beyond the F-35 and S-400 to include conflicting strategies in Syria, sanctions on Iran and the detention of US consular staff in Turkey.
