PARIS: United States President Donald Trump and his Turkish counterpart Tayyip Erdogan discussed how to respond to the killing last month of Saudi Arabian dissident Jamal Khashoggi, a White House official said on Sunday.

The conversation took place during a Saturday dinner with heads of state gathered in Paris to mark the World War One Armistice centenary.

Trump expects to form a “much stronger opinion” by next week on Khashoggi’s killing and Washington’s response, he said on Nov. 7 – adding that he was working with Congress, Turkey and Saudi Arabia to establish who bore responsibility.
