The Houthis said they launched a missile attack targeting Riyadh's King Khalid International Airport and other sites, again showing their ability to strike deep into the neighboring kingdom amid the stalemated war in Yemen, the Arab world's poorest country.
The rebel group, who are called as Houthis, fired a ballistic missile into territory of Saudi over many times since the past three years.
The footage shows an intense escalation, just days after Yemeni rebels took down a Saudi coalition aircraft with an R-27 air-to-air rocket reportedly modified into a surface-to-air missile.
"With credit to the Saudi Royal Air Defense Forces, all seven ballistic missiles were intercepted and destroyed".
"The Saudis have directly blamed the Iranians for previous missile launches, so I expect MbS will bring this up with his US counterparts", Graham Griffiths, senior analyst at Control Risks Middle East, said in reply to emailed questions.
Several loud explosions were heard in Riyadh.
Yemeni revolutionaries fired a barrage of ballistic missiles of different ranges on four airports across Saudi Arabia, on the third anniversary of the aggression on Yemen launched by Saudi-led coalition.
"Britain undoubtedly has direct responsibility for the war crimes committed over the past three years in Yemen by selling arms and providing logistical and intelligence support to the countries attacking Yemen", said foreign ministry spokesman Bahram Ghasemi on the ministry's website. Coalition spokesman Col. Turki al-Malki told a news conference in Riyadh that Sunday's missile attacks were a clear violation of global law and accused the Houthis of smuggling weapons from Iran.
The war began in March 2015 when the coalition began pounding the Houthis with air strikes after they took control of the capital, Sana'a.
The shrapnel fell on a residential house causing the death of a resident and injury of two others, all of them of Egyptian nationality.
The UN has also dispatched an envoy to meet with warring parties in its quest to facilitate a negotiated political settlement to the crisis, which has left an estimated 22.2 million people in dire need of humanitarian assistance. The Burqan missile is an Iranian-modified scud missile.
Iran has repeatedly denied arming the Huthis in Yemen, despite claims by the United States and Saudi Arabia that the evidence of an arms connection is irrefutable.
Mr Guterres is due to meet Saudi Crown Prince Mohammed bin Salman, who is on a visit to the USA, at United Nations headquarters in NY on Tuesday to discuss Yemen.
The poll comes as some European states, notably Germany, have curtailed ties with the Saudi-led military coalition.
