Saudi Arabia’s foreign ministry has said it is a matter of “great concern” that 9/11 relatives in the US may be able to sue the kingdom for damages.
On Wednesday the US Congress voted for a law allowing families of nearly 3,000 people killed in the attacks to sue.
In doing so they overrode a veto by President Barack Obama, who said it would set a”dangerous precedent”.
Fifteen of the 19 hijackers that day were Saudi nationals, but the kingdom has denied any role in the attacks.
In a statement, the country’s foreign ministry said:
“The erosion of sovereign immunity will have a negative impact on all nations, including the United States.”
