Four commercial ships were targeted by sabotage near UAE waters .

The UAE Ministry of Foreign Affairs announced no casualties have been reported after 4 commercial ships were subject to “sabotage operations” within UAE territorial waters.

Earlier, Fujairah Emirate Sea Port Media Office denied media reports that explosions took place at the Port of Fujairah.

The incident occurred near the UAE emirate of Fujairah, it said, one of the world’s largest bunkering hubs which lies just outside the Strait of Hormuz. The strait is a vital oil and natural gas corridor for the global energy market.

“Subjecting commercial vessels to sabotage operations and threatening the lives of their crew is considered a dangerous development,” the ministry statement said.

It gave no details about the nature of the sabotage and did not identify the vessels beyond saying they were of various nationalities. It said the incident did not result in spills.

The statement did not say who carried out the operations and made no mention of Iran, amid escalating tension in the region after the U.S. military sent forces, including an aircraft carrier, to the Middle East.
