DUBAI, United Arab Emirates — Crew members from a Norwegian-owned oil tanker apparently attacked in the Gulf of Oman landed Saturday in Dubai after two days in Iran as the other tanker targeted in the assault limped into anchorage off the eastern coast of the United Arab Emirates.

Both the mariners’ recollection and the physical evidence remaining on the MT Front Altair and the Kokuka Courageous, now off the coast of Fujairah, will play an important role in determining who the international community blames for Thursday’s explosions on board the oil tankers.

Already, the U.S. has blamed Iran for what it described as an attack with limpet mines on the two tankers, pointing to black-and-white footage it captured that American officials describe as Iranian Revolutionary Guard troops removing an unexploded mine from the Kokuka Courageous.

Tehran rejects the allegation, instead accusing the U.S. under President Donald Trump of pursuing an “Iranophobic” campaign against it. However, Iran previously used mines against oil tankers in 1987 and 1988 in the “Tanker War,” which saw the U.S. Navy escort ships through the region — something American officials may consider doing again.

In a new allegation Saturday, the U.S. military accused Iranian Revolutionary Guard troops of trying but failing to shoot down a U.S. drone to disrupt surveillance of the tankers during the attacks.

All this comes after four other oil tankers off Fujairah suffered similar attacks in recent weeks, and Iranian-allied rebels from Yemen have struck U.S. ally Saudi Arabia with drones and missiles.

Late Saturday, Yemen’s Iranian-backed Houthi rebels claimed a new drone attack targeting Saudi Arabia, the latest in their recent campaign that has stepped up amid the Mideast tensions. Yahia al-Sarie, a Houthi spokesman, said their drones targeted airports in Jizan and Abha in Saudi Arabia. Early Sunday, the Saudi-led coalition fighting in Yemen said it shot down a drone near the Abha regional airport, but did not acknowledge the Jizan claim.

The Houthis say they launched a cruise missile that struck the Abha airport Wednesday, an attack Saudi Arabia says wounded 26 people.

Trump withdrew America last year from the 2015 nuclear deal that Iran reached with world powers and recently imposed a series of sanctions now squeezing its beleaguered economy and cutting deeply into its oil exports. While Iran maintains it has nothing to do with the recent attacks, its leaders repeatedly have threatened to close the vital Strait of Hormuz, through which 20 percent of the world’s oil flows.

On Saturday, Associated Press journalists saw the crew members of Front Altair after their Iran Air flight from Bandar Abbas, Iran, landed at Dubai International Airport. Ten of its 23 mariners walked out to be greeted by officials who earlier could be heard saying the others would be catching connecting flights.

The officials repeatedly refused to identify themselves to journalists. They and the mariners declined to take questions.
