Saudi Arabia has strongly denounced US Senate resolutions which called for an end to American support for Saudi forces in Yemen and blamed Crown Prince Mohammed bin Salman for the murder of Jamal Khashoggi.

The kingdom released an unusually forceful statement after both Democrat and Republican senators defied the White House and voted through the largely symbolic resolutions criticising Saudi Arabia.

"The Kingdom categorically rejects any interference in its internal affairs, any and all accusations, in any manner, that disrespect its leadership... and any attempts to undermine its sovereignty or diminish its stature,” the Saudi foreign ministry said.

While Donald Trump has said he plans to stand by Saudi Arabia, the US-Saudi relationship is under increasing scrutiny from Congress and the American public after the death of Mr Khashoggi, a Washington Post columnist.

The Senate resolutions have no legal weight but will add to pressure on Mr Trump over his administration’s close ties to the kingdom’s leaders.
