The US Senate has passed a resolution blaming and condemning Saudi Arabia's Crown Prince Mohammed bin Salman for the murder of journalist Jamal Khashoggi, ratcheting up pressure on President Donald Trump who has aligned himself with the Saudi kingdom in the aftermath of the ghastly killing.

The Senate on Thursday delivered back-to-back rebukes of the Trump administration's handling of relations with Saudi Arabia, first voting to end the US participation in the Saudi-led war in Yemen and then unanimously approving the measure blaming Crown Prince Mohammad bin Salman for murdering Khashoggi who was critical of his policies.
