Riyadh's residents have been a given green light after air raid alerts were issued and explosions were reported in the capital.
It was the first time alerts had been issued in Saudi Arabia's capital since the Houthis increased their attacks and declared a "maritime embargo" on the Saudis in July.
The Saudi Civil Defence sent alerts for the capital and several other regions late on Friday night and Saturday morning (local time) as the Kingdom's conflict with the Iran-backed Houthis continued to escalate.
Journalists from Reuters and AFP reported hearing explosions in the capital, but authorities have since said the danger has passed.
Residents were urged to avoid gathering in crowds.
Houthis taking control of strategic ports
The Houthis recently seized control of the strategic port city of Mokha and Perim Island, a gateway to a key shipping route used by the Gulf state to export to Asia and Europe.
As per the Iran-backed group's spokesman, the blockage was in retaliation for a Saudi blockade of ports and airports in Houthi-controlled north-western Yemen.
Saudi vessels have relied on that stretch of the Red Sea for oil exports since the US and Israel's war with Iran effectively closed the Strait of Hormuz.
The Houthis attacks Saudi oil facilities
Last week, the Houthis attacked several Saudi oil facilities with drones and missiles, causing fires which led to operations being temporarily halted.
The attacks have heavily impacted global energy markets, leading to the hike in the price of petrol an diesel in several countries, which were already impacted due to blockades of the Strait of Hormuz.
President Trump refused to involve the US in the conflict?
As reported by CBS News, sources have claimed that Saudi Crown Prince Mohammed bin Salman has personally asked US President Donald Trump to take military action against the Houthis, with the president declining to involve the US military directly in the conflict.
However, insiders shared the President instead offered to assist with intelligence and targeting support.
