>> Turkish president Tayyip Erdogan will meet Donald Trump in the White House on Tuesday, for a meeting which has been overshadowed by US decision to arm Kurdish YPG militia in Syria. I'm Dominic Evans for Reuters in Istanbul. This is the first meeting between Erdogan and Trump. When Trump was elected in November last year, Erdogan welcomed his election, said he hoped it would have beneficial impact on the Middle East.
And Trump congratulated Erdogan last month when he won a referendum which granted him sweeping new powers, so it looks like they were set for a positive meeting. That all changed last week with the decision to arm the YPG, which has angered Turkey. Turkey sees the YPG as an extension of another Kurdish group, the PKK, which has been fighting a 30-year insurgency in South-East Turkey.
Turkish officials say arming the YPG, is a direct security threat against Turkey. President Erdogan has said he will try to change Donald Trump's mind at their meeting at the White House on Tuesday. This matters a great deal to Turkey, so much so that one Turkish official described the decision to arm the YPG as putting dynamite under the relations between the two countries.
So this will be very much the focus for the Turkish side, to either change or at least soften the extent of support that the US gives the the YPG.
