A report by the BBC News Arabic service argues that the impact of the Yemen war is no longer confined to the country. It affects global trade, oil prices and food supplies.
The report presents five key stages to explain the roots, evolution and consequences of the war, from the Middle East to the global economy.
According to the report, Yemen has been in a complex war for more than a decade. Internal divisions have intertwined in this war with regional rivalry between Saudi Arabia and Iran, according to the report.
According to BBC News Arabic, the importance of two maritime passages, Bab al-Mandab and the Strait of Hormuz, has grown as tensions in the region have risen. A large share of global trade and energy supplies passes through these two passages, according to the report.
The report describes Ansar Allah as having become an influential player in regional security and international navigation. It also refers to attacks on shipping lanes. The text does not specify the details of these attacks, their dates or their numbers.
