Level 1 — Absolute Beginner
Yemen's Houthi group said it will stop ships from going to Saudi Arabia. They want to close a narrow sea road called the Bab el-Mandeb strait.
Two big ships with Saudi oil turned around. They did not want to sail through the dangerous strait. The ships had 2.7 million barrels of oil.
This is a new problem next to another sea road, the Strait of Hormuz, where Iran and the United States are already fighting.
In Washington, a leader named Pete Hegseth told Congress that the war with Iran has already cost 37.5 billion dollars. He asked for more money.

Level 2 — Elementary
Yemen's Iran-backed Houthi movement declared a maritime blockade against Saudi Arabia on Monday, threatening to attack any ship that loads or unloads cargo at a Saudi port anywhere within its reach.
The warning had an immediate effect. Two tankers that had loaded Saudi crude oil at the Red Sea port of Yanbu, the Xin Long Yang and the Rodos, changed direction on Tuesday. Instead of sailing south through the Bab el-Mandeb strait toward the Indian Ocean, both ships turned north toward the Suez Canal. Together they were carrying about 2.7 million barrels of oil.
The Bab el-Mandeb sits at the southern end of the Red Sea, between Yemen and the Horn of Africa. It has become an important route for Saudi oil that was already being rerouted away from the Strait of Hormuz, which Iran has targeted during the ongoing war with the United States.
On the same day, US Defense Secretary Pete Hegseth told the Senate Appropriations Committee that the war with Iran has cost about 37.5 billion dollars so far, as the Pentagon asked lawmakers for 67 billion dollars in additional funding.

Level 3 — Intermediate
Yemen's Iran-backed Houthi movement escalated the regional oil crisis on Monday by declaring a maritime blockade against Saudi Arabia, warning shipping companies in an email that any vessel loading or unloading cargo at a Saudi port would be considered a legitimate target and could be attacked anywhere within the group's operational range.
The threat produced an immediate and measurable response. Two tankers that had loaded Saudi crude at the Red Sea port of Yanbu for buyers in China and India, the Xin Long Yang and the Rodos, abandoned their planned route on Tuesday. Rather than continuing south through the Bab el-Mandeb strait into the Indian Ocean, both vessels turned north toward the Suez Canal, together diverting roughly 2.7 million barrels of crude.
The move strikes directly at a route that had been absorbing Saudi oil diverted away from the Strait of Hormuz, which Iran has targeted repeatedly since its war with the United States began. With Hormuz effectively contested and now Bab el-Mandeb under threat, Saudi Arabia faces pressure on two of the world's most important oil chokepoints simultaneously.
The same day, Defense Secretary Pete Hegseth testified before the Senate Appropriations Committee that the conflict with Iran has cost approximately 37.5 billion dollars to date, as the Pentagon requested 67 billion dollars in supplemental funding. Democratic lawmakers and a source familiar with internal Pentagon estimates told reporters the real total, once base repairs and weapons replenishment are included, could run as high as 80 to 100 billion dollars.
- escalate
- to make a conflict or crisis grow more serious or intense
- legitimate

- divert
- to cause something to change direction or take a different route
- contested
- disputed or fought over by opposing sides
- supplemental
- added to something else to complete or improve it
- replenish
- to fill something up again after it has been used or depleted
- simultaneously
- happening or existing at the same time
Level 4 — Advanced
Yemen's Iran-aligned Houthi movement widened the regional oil crisis on Monday, declaring a maritime blockade against Saudi Arabia and warning shipping firms, in a message circulated to industry contacts, that any vessel loading or discharging cargo at a Saudi port would be treated as a prohibited target liable to attack anywhere within the group's operational reach.
The threat produced swift and quantifiable consequences. Two tankers, the Xin Long Yang and the Rodos, which had taken on Saudi crude at the Red Sea port of Yanbu bound for customers in China and India, abandoned their intended passage on Tuesday, reversing course north toward the Suez Canal rather than continuing south through Bab el-Mandeb into the Indian Ocean. Combined, the vessels were carrying an estimated 2.7 million barrels, a modest fraction of global supply but a symbolically significant test of the blockade's credibility.
The gambit is calculated to strike at precisely the corridor that had been absorbing Saudi crude diverted away from the Strait of Hormuz, which Iran has repeatedly targeted since its war with Washington began earlier this year. With Hormuz effectively contested and Bab el-Mandeb now under an explicit threat, the kingdom confronts simultaneous pressure on two of the maritime industry's most consequential chokepoints, a scenario energy analysts had long treated as a worst-case contingency rather than an imminent likelihood.
The same day, Defense Secretary Pete Hegseth appeared before the Senate Appropriations Committee and put the conflict's cost to date at approximately 37.5 billion dollars, as the Pentagon pressed lawmakers for 67 billion dollars in supplemental appropriations. Democratic committee members, along with a source with direct knowledge of internal departmental accounting, told reporters the comprehensive figure, once military construction for damaged bases, aircraft replacement, and full weapons replenishment are tallied, could ultimately range between 80 and 100 billion dollars, a discrepancy that underscored the difficulty of pricing an open-ended conflict in real time.
