BEIRUT — Explosions aboard a pair of oil tankers in the Gulf of Oman on Thursday heightened regional tensions with Iran in an already volatile showdown with Washington and sent energy prices soaring in jittery global markets.

U.S. Secretary of State Michael R. Pompeo quickly blamed Tehran for what he called “a blatant assault” and cited the action as the “terror, bloodshed and extortion” that is part of Iranian strategy.

The apparent attacks, a month after four other tankers were damaged in mine explosions that the Trump administration also blamed on Iran — without providing evidence — sharply raised fears in the strategically important region that Washington might use such incidents to punish the Islamic Republic even without ironclad proof of its involvement.

Pompeo told reporters in Washington that the assessment was based on U.S. intelligence, the type of weapons used, the level of expertise needed and that none of Iran’s proxy groups, which operate in countries across the region, had the resources to carry out an apparent attack like Thursday’s.

“These attacks are a threat to international peace and security, a blatant assault on the freedom of navigation, and an unacceptable escalation of tension by Iran,” Pompeo said.

He did not elaborate, offer details or take questions in his brief appearance before reporters at the State Department.

U.S. military officials said later there was evidence the Iranians carried out the attacks using mines.

To bolster that claim, late Thursday the military released video taken by a Navy surveillance plane that it said showed a crew from an Iranian patrol boat removing an unexploded mine from the hull of the Kokura Courageous 10 hours after the ship was stricken by an explosion.

The grainy black and white video shows a small boat alongside the tanker. Several crew members are seen near the bow as one pulls a small object off the hull.

At 4:10 p.m. a patrol boat from Iran’s Islamic Revolutionary Guard Corps approached the Kokura Courageous and “was observed and recorded removing the unexploded limpet mine,” said the statement by Capt. Bill Urban, a spokesman for U.S. Central Command.

A limpet mine is a naval weapon that attaches to a ship with magnets.

Urban said the U.S. also observed Iranian small boats swarmed around the other damaged tanker, the Front Altair, demanding that the ship’s crew, who had been rescued by another vessel, be turned over to them.

The rescuers, from a ship called the Hyundai Dubai, “complied with the request and transferred the crew” to the Iranians, Urban said.

Hours earlier, dozens of crew members were rescued after explosions on the Japanese-owned Kokuka Courageous and the Front Altair, owned by Norway. Iran has denied any connection with the incident.

The suspected attack on a Japanese-owned vessel came less than a day after Japanese Prime Minister Shinzo Abe made a rare conciliatory visit to Tehran seeking dialogue.

The United States and its Persian Gulf allies, led by Saudi Arabia, have mounted a steady campaign of diplomatic isolation and economic punishment of Iran, which they blame for militancy in the Middle East.

Pompeo said he was instructing U.S. envoys to stress the issue in a Security Council meeting, while the United Nations’ top diplomat separately urged a return to calm.

“I strongly condemn any attack against civilian vessels. Facts must be established, and responsibilities clarified,” said U.N. Secretary-General Antonio Guterres in a Security Council meeting on cooperation with the Arab League.

“If there is something the world cannot afford, it is a major confrontation in the Gulf region,” Guterres said.

Ahmed Aboul Gheit, the Arab League’s secretary-general, warned there were sides seeking to “inflame the region, and practice a kind of dangerous blackmail of the international community.”

The Egyptian also called upon the U.N. Security Council to confront whoever is behind the suspected attack so the perpetrator could face “all legal responsibility.”

On Thursday morning, the Front Altair and the Kokuka Courageous were sailing in international waters in the Gulf of Oman when they suffered apparent attacks about 25 miles off the southern coast of Iran that led to explosions on board.

The Front Altair reported three detonations, according to a statement Thursday from the Norwegian Maritime Authority. It was not clear what caused the blasts, but they were serious enough to cause a major fire.

Images depicted the Front Altair engulfed in a 15-mile plume of smoke that was captured by NASA satellites; later pictures showed more than a third of the deck scorched, and a video showed a raging fire in the ship’s center.

The crews — 23 on the Front Altair and 21 on the Kokuka Courageous — were forced to abandon their ships, but had been evacuated and were safe, according to press statements by the vessels’ owners.

The U.S. Navy, according to a statement released by U.S. Central Command, had rescued the 21 mariners from the Japanese vessel.

Iran earlier had said that it had rescued all 44 of the ships’ crew members.

Sailors aboard the Bainbridge, the U.S. Navy destroyer that went to assist the Kokuka Courageous, saw a device that appeared to be an unexploded mine above the waterline on the hull of the tanker and photographed it, a U.S. official said.

After the captain of the Kokuka Courageous was alerted to the device, he ordered the crew to abandon the damaged ship, a U.S. official said.

Possible use of naval mines to attack the tankers was one piece of information that led U.S. intelligence agencies to reach a preliminary conclusion that Iran’s Islamic Revolutionary Guard Corps was responsible for the alleged attacks, one of the officials said.

Last month, Trump administration officials blamed Iran for suspected attacks that damaged four oil tankers off the United Arab Emirates, citing undisclosed evidence that the Revolutionary Guard carried out the attacks using limpet mines.

U.S. national security adviser John Bolton has promised to provide evidence to the Security Council proving Iran’s culpability, but has yet to do so.

Regardless of who was behind Thursday’s suspected attacks, they triggered a 3% increase in world energy prices.

The explosions occurred near the Strait of Hormuz, which serves as a crucial passageway for much of the oil from Gulf states. At its narrowest it measures a mere 21 nautical miles, yet in 2016 it ushered through some 18.5 million barrels of oil per day, according to the U.S. Energy Information Administration.

Those numbers make it an important choke point; any conflict there would have a staggering effect on trade.

While details of Thursday’s suspected attacks were not clear, said the Norwegian Maritime Authority, it urged Norwegian ships to “exercise extreme caution in the region” and to “keep a safe distance from Iranian waters.” It also raised its security level in the area.

Also unclear was what Iran would gain from such an assault — coinciding with Abe’s high-profile visit to Tehran aimed at salvaging the 2015 international nuclear deal.

Both ships, according to the Japanese government, were carrying “Japan-related” cargo, leading Iranian Foreign Minister Javad Zarif to question the timing of Thursday’s apparent attacks.

“Suspicious,” he tweeted, “doesn’t begin to describe what likely transpired this morning.”

Meanwhile, Abe had brought a message from President Donald Trump to Ayatollah Ali Khamenei, Iran’s supreme leader.

Khamenei rejected the letter, saying Iran had “no trust” in the U.S. and that it would “not repeat the bitter experience” of negotiations, in a reference to the 2015 nuclear deal that was repudiated by Trump.

Khamenei also said he considered Trump an unworthy person with whom to strike up a correspondence.

“I do not have and will not have any response for him,” said Khamenei.

Nevertheless, he again emphasized Iran was not seeking the development or use of nuclear weapons.

The Trump administration’s quick public assertion that Iran was behind the latest suspected attacks concerned some senior U.S. officers, who said they feared that the administration was moving too quickly toward retaliating, possibly with military force, without building a public case that Tehran was responsible.

Another option for the U.S. short of military action would be to seek to build international support for steps to safeguard shipping traffic, using naval ships from the U.S. and other countries to escort tankers and other vessels through the Persian Gulf and into the Arabian Sea.

Pentagon officials said they were worried that Iran and its proxies could conduct its own reprisals against U.S. forces or allies in the region if Washington escalates the confrontation.

“We will defend our interests, but a war with Iran is not in our strategic interest, nor in the best interest of the international community,” said Army Lt. Col. Earl Brown, a spokesman for U.S. Central Command, which oversees military operations in the Middle East.

The Pentagon, nevertheless, has substantially increased its forces in the region recently.

Early last month, the aircraft carrier Abraham Lincoln and its strike group of ships arrived in waters near the Persian Gulf in response to what U.S. officials said was intelligence suggesting Iran was preparing attacks.

In late May, a fighter squadron, manned and unmanned reconnaissance aircraft, engineering units and additional Patriot anti-missile batteries — comprising 1,500 troops altogether — were added. An amphibious assault ship with a Marine expeditionary unit and an Air Force B-52 bomber task force were also sent.

Another amphibious assault ship, the Arlington, with Marines aboard, arrived in the Arabian Sea this week.

Those forces are in addition to the more than 30,000 troops stationed in the region, along with hundreds of fighters and bombers at air bases in Persian Gulf countries.

Critics warned that Trump administration reliance on military pressure, sanctions and other tactics against Iran carried risks.

“If Iran is behind these attacks, it clearly shows that a U.S. policy relying solely on coercion can backfire,” Ali Vaez, senior Iran analyst and Iran project director for the International Crisis Group, said in a statement. “Diplomatic efforts by allies are necessary to dial down the tension, but they can’t resolve it as long as Washington relies on an all-or-nothing approach.”
