WASHINGTON - The US Senate delivered a rare double rebuke to President Donald Trump on Saudi Arabia on Thursday, voting to end US military support for the war in Yemen and blame the Saudi crown prince for the murder of journalist Jamal Khashoggi.

The votes were largely symbolic because to become law the resolutions would have to pass the House of Representatives, whose Republican leaders have blocked any legislation intended to rebuke the Saudis.

In a historic move, Senators voted 56-41 to end US military support for the Saudi-led coalition in Yemen's civil war. The conflict has killed tens of thousands of people and spawned what the United Nations calls the world's most dire human crisis, with the country on the brink of famine.

It was the first time either chamber of Congress had backed a resolution to withdraw US forces from a military engagement under the War Powers Act. That law, passed in 1973, limits the president's ability to commit US forces to potential hostilities without congressional approval.

Seven of Trump's fellow Republicans joined Senate Democrats to back the measure.

Immediately after the Yemen vote, the Senate backed a resolution blaming Saudi Crown Prince Mohammed bin Salman for Khashoggi's murder and insisting that Saudi Arabia hold accountable anyone responsible for his death.

Khashoggi, a US resident who was a columnist for the Washington Post, was killed inside the Saudi consulate in Istanbul in October. The Senate vote, which was unanimous, puts pressure on House leaders to allow a vote on the Khashoggi resolution this month, before Congress adjourns for the year.

"Unanimously, the United States Senate has said that Crown Prince Mohammed bin Salman is responsible for the murder of Jamal Khashoggi. That is a strong statement. I think it speaks to the values that we hold dear," said Republican Senator Bob Corker, chairman of the Foreign Relations Committee and sponsor of the resolution.

Trump has said he wants Washington to stand by the Saudi government and the prince, despite a CIA assessment it was likely he ordered Khashoggi's killing. He promised to veto the war powers resolution.

Opponents of the resolution are reluctant to take any action to disrupt the strategic US relationship with Saudi Arabia, seen as an essential counterweight in the Middle East to Iran, arch-enemy of close US ally Israel.

Administration officials also see Saudi support as a linchpin for an Israeli-Palestinian peace plan yet to be unveiled by the Trump administration. And they have argued that ending US support could complicate Yemen peace talks.
