According to a report by the Wall Street Journal, the planes were struck while they were on the ground at the Prince Sultan Air Base, a major facility hosting US forces in Saudi Arabia.

The aircraft sustained damage during the missile attack, the report added.

The report said that the attack occurred amid missiles and drone strikes launched by Iran targeting US military installations in the region.

The damaged planes were identified as Boeing KC‑135 Stratotanker aircraft manufactured by Boeing.

The report noted that although the aircraft were damaged in the missile strike, they were not completely destroyed and are currently undergoing repairs. No casualties were reported in the incident.

Prince Sultan Air Base is located about 70km southeast of Riyadh, the capital of Saudi Arabia.

The incident is being seen as part of a series of recent setbacks for the United States Air Force in the region.

Earlier, two KC-135 refuelling aircraft collided during an operation, causing one of the planes to crash.

The Pentagon confirmed that all six personnel aboard the aircraft destroyed in the collision were killed.

Following the latest incident, the number of US aerial refuelling aircraft damaged or destroyed in recent days has risen to at least seven.
