The tanker attacks off the coast of the United Arab Emirates were "Israeli mischief," an Iranian parliamentary spokesman said on Tuesday, according to the Islamic Republic News Agency (IRNA).
"The events that took place in the Emirates were Israeli mischief," Behrouz Nemati said, without providing any details on what role Israel may have played in the attacks.
Saudi Arabia said on Monday that two of its oil tankers were among those attacked off the coast of the Emirates and described it as an attempt to undermine the security of crude supplies amid tensions between the United States and Iran.
The UAE said on Sunday that four commercial vessels were sabotaged near Fujairah emirate, one of the world's largest bunkering hubs lying just outside the Strait of Hormuz. It did not describe the nature of the attack or say who was behind it.
Meanwhile, satellite images obtained by The Associated Press on Tuesday showed no major visible damage to the vessels.
Details of the alleged sabotage to two Saudi, one Norwegian and one Emirati oil tanker on Sunday remained unclear, and Gulf officials have declined to say who they suspected was responsible. But it demonstrated the raised risks for shippers in a region vital to global energy supplies as tensions are increasing between the U.S. and Iran over its unraveling nuclear deal with world powers.
The U.S. has warned sailors of the potential for attacks on commercial sea traffic, and regional allies of the United Arab Emirates condemned the alleged sabotage as the tankers were off the coast of the UAE port city of Fujairah.
A U.S. official in Washington, without offering any evidence, told the AP that an American military team's initial assessment indicated Iran or Iranian allies used explosives to blow holes in the ships.
The official, who was not authorized to discuss the investigation, agreed to reveal the findings only if not quoted by name. The U.S. Navy's 5th Fleet, which patrols the Middle East and operates from a base in Fujairah, has repeatedly declined to comment.
