Level 1 — Absolute Beginner
There is a narrow sea road near Yemen. It is called Bab el-Mandeb. Many oil ships use it.
A group called the Houthis is now strong there. They took some islands in September. They also took a port city named Mocha.
Iran also keeps another sea road closed. It is the Strait of Hormuz. On Monday, October 5, one tanker turned back after Iranian forces threatened it.
Oil prices stay high. A barrel of Brent oil costs about 100 dollars.

Level 2 — Elementary
The Houthis, a group that Iran supports, are tightening their hold on the Bab el-Mandeb Strait at the southern end of the Red Sea. They took islands in the strait in mid-September and have now captured the port city of Mocha.
Late last month the group also attacked targets in Saudi Arabia, including the area near the port of Yanbu. Reports say an important Saudi oil pipeline that carries crude to the Red Sea was damaged and may be out of service for weeks.
On Monday, Brent oil stayed near 100 dollars a barrel. Reports were mixed about a new strike on the pipeline. Meanwhile, Iran says the Strait of Hormuz stays closed, and a tanker turned back after being threatened by Iranian forces, according to the British navy.
There is one small piece of good news. Recent data show that crude oil is moving through Hormuz at about 13.5 million barrels a day, the same as before the war. But fuel shipments are still limited.

Level 3 — Intermediate
Iran-aligned Houthi forces are tightening their grip on the Bab el-Mandeb Strait, the gateway between the Red Sea and the Gulf of Aden. After seizing islands in the strait in mid-September, they have now taken the Yemeni port of Mocha, a move analysts say deepens their hold over one of the world's most important shipping lanes.
The pressure now reaches Saudi Arabia. The group claimed attacks on Saudi facilities late in September, with the Red Sea port of Yanbu among the targets, and strikes on the kingdom's East-West pipeline have raised fears that it could be out of action for weeks. On Monday, conflicting reports circulated about a fresh strike on the line.
Markets reacted cautiously. Brent crude hovered around 100 dollars a barrel on Monday, well below its September spike above 106 dollars but far above where it traded before the war. In the Strait of Hormuz, Iran insists the waterway remains closed, and the United Kingdom Maritime Trade Operations centre said a tanker turned back after being threatened by Iranian forces.
The picture is not uniformly grim. Crude exports through Hormuz have climbed back to roughly prewar levels, about 13.5 million barrels a day, according to recent tracking data. Yet fuel shipments such as diesel and jet fuel remain constrained, and traders warn that a second chokepoint under pressure at the same time leaves little room for error.
- aligned

- Buildings or sites used for a purpose.
- circulated
- Spread from person to person.
- spike
- A sudden sharp rise.
- constrained
- Held back or limited.
- chokepoint
- A narrow place that controls the movement of goods.
Level 4 — Advanced
The Houthis' capture of the Yemeni port of Mocha, following their seizure of islands in the Bab el-Mandeb Strait in mid-September, tightens the movement's grip on the southern mouth of the Red Sea and gives Iran's regional network a second maritime lever just as the first, the Strait of Hormuz, remains officially shut by Tehran.
The strategic logic is difficult to miss. Late-September claims of attacks on Saudi facilities, with the Red Sea terminal of Yanbu among them, and strikes on the East-West pipeline that bypasses Hormuz, have raised the prospect that Saudi Arabia's principal alternative export route could be impaired for weeks, although reports about a fresh strike on Monday were contradictory.
Brent crude, hovering around 100 dollars a barrel, has so far priced in disruption rather than panic, sitting below its September peak above 106 dollars. Beneath that calm lies fragility: the United Kingdom Maritime Trade Operations centre reported that a tanker turned back after Iranian forces threatened it, even as Hormuz crude flows, at roughly 13.5 million barrels a day, have returned to prewar levels while refined fuel shipments remain constrained.
For markets and governments alike, the lesson is that rerouting is not a solution when both routes can be pressured at once. Rhetoric from Tehran, including parliament speaker Mohammad Bagher Ghalibaf's warning that anyone who strikes Iranian assets will be struck in return, suggests no one expects a quick de-escalation.
