US Ambassador to the United Nations Nikki Haley said a missile fired by Yemen’s Houthi group toward Riyadh on Tuesday "bears all the hallmarks of previous attacks using Iranian-provided weapons," Al Alarabiya TV channel reported on Tuesday.

"If we do nothing about the missiles fired at Saudi Arabia, we will not be able to stop the violence," warned Haley.

"There is clear evidence that the missiles that landed on Saudi Arabia come from Iran," she said, stressing the need to adopt a new international resolution that increases pressure on Tehran.
