Two residents in Dhahran told Reuters they had heard an explosion. The U.S. mission in Saudi Arabia issued an advisory, citing reports of possible missile attacks and explosions on Sunday evening in the tri-city area of Dhahran, Dammam and Khobar in Saudi Arabia's Eastern Province.
The kingdom's Eastern Province is home to most of Saudi Aramco's oil production and export facilities.
Houthi military spokesman Yahya Sarea said the group fired 14 drones and eight ballistic missiles across the border with the kingdom in a "wide operation in the heart of Saudi Arabia".
Earlier, the Saudi-led coalition said it conducted air strikes on Houthi military targets in Sanaa and other regions and warned that "civilians and civilian objects in the Kingdom are a red line".
