Two oil tankers have collided in the Strait of Hormuz, the world’s most critical oil checkpoint just off the coast of Iran, Al Jazeera reported.

British maritime security monitor Ambrey said the collision on Tuesday of the Adalynn and the Front Eagle is “not security-related,” despite the proximity of the accident to the war raging between Israel and Iran and concerns over its impact on navigation.

Shipping company Frontline said a fire was extinguished on the Front Eagle tanker, 15 nautical miles (28km) off the UAE’s Gulf of Oman coast. It added that no pollution had been detected.

The United Arab Emirates coastguard said it had evacuated 24 people from the Adalynn oil tanker.

The Front Eagle was loaded with 2 million barrels of Iraqi crude oil and was en route to Zhoushan in China, according to monitoring service TankerTrackers.com.

The Adalynn, a Suezmax-class tanker owned by India-based Global Shipping Holding Ltd, had no cargo and was sailing towards the Suez Canal in Egypt, the monitoring service said.
