The British prime minister says she intends to talk about the killing of Washington Post columnist Jamal Khashoggi with Saudi Crown Prince Mohammed bin Salman at the G-20 meeting in Argentina.

Theresa May said on the airplane to Buenos Aires that the British government “wants to see a full and transparent investigation in relation to what happened and obviously those responsible being held to account.”

The Guardian, a British newspaper, said Downing Street sources have not officially confirmed a bilateral meeting but have suggested that May and the crown prince would be “engaging.”
