Four consecutive loud booms were heard in Saudi Arabia’s capital Riyadh on Wednesday, Reuters witnesses said.
According to official Saudi figures, 31 missiles have been intercepted since March 26, while a total of 135 missiles have been shot down since the kingdom launched its military campaign in Yemen in 2015, mostly near the border.
The United Nations, Western nations and Saudi Arabia say Iran supplies the Houthis with long-range missiles capable of reaching Riyadh. Iran denies arming them.
The stalemated war in Yemen has killed more than 10,000 civilians and displaced 3 million others, pushing the Arab world’s poorest country to the brink of famine. Saudi Arabia has also imposed an air and sea blockade on Yemen.
The U.S., which is one of the kingdom’s most important military suppliers, has backed the coalition with logistical support.
