In early September 2026, Iran-backed Houthi rebels announced they had seized Perim Island in the Red Sea, a small landmass at the southern entrance to the Bab al-Mandab Strait. The strait is one of the world's most critical maritime chokepoints, connecting the Gulf of Aden to the Red Sea and providing the alternative route to the Suez Canal for oil tankers unable to pass through the Strait of Hormuz.
The first paragraph establishes that the Bab al-Mandab Strait is a critical chokepoint connecting the Gulf of Aden to the Red Sea and offering an alternative route to the Suez Canal for oil tankers unable to pass through the Strait of Hormuz. This map places the strait within the broader network of global shipping routes.
The Houthis said in a statement that 'maritime navigation is safe for all companies except for Saudi vessels,' effectively declaring a blockade against Saudi-linked shipping. They also claimed the operation was a 'success' and that they had expelled 'Saudi-backed forces' from Yemen's western coast. A Yemeni government source told the BBC that the Houthis had taken control of the island as part of a 'large-scale' military operation.
The second paragraph reports that the Houthis claimed to have expelled Saudi-backed forces from Yemen's western coast as part of a large-scale military operation. This map illustrates the territorial extent of Houthi control along that coast.
The implications extend beyond the immediate region. Because Saudi Arabia has increasingly relied on the Red Sea route after the Strait of Hormuz was effectively closed due to the Israel-Iran conflict, any disruption to the Bab al-Mandab Strait could squeeze global oil supplies. The BBC reports that at least 46,000 people have been displaced in Yemen since fighting escalated the previous week, according to the International Organization for Migration. The United States has offered intelligence and targeting support to Saudi Arabia but has said it is not prepared, at least for now, to take direct military action. Saudi Crown Prince Mohammed bin Salman reportedly asked former US President Donald Trump to intervene militarily, but Trump declined, two sources familiar with the matter told the BBC's US partner CBS News.
Analysts read the Houthis' explicit limitation of their threat to Saudi vessels as a calculated signal to Washington: maximum pressure on Riyadh without giving the United States an immediate reason to enter the conflict directly. Whether this distinction can hold if fighting escalates remains uncertain.
Perim Island divides the Bab al-Mandab Strait, the southern gateway to a trade route that links Asia and Europe. The island sits at the juncture where ships heading to the Suez Canal from the Gulf of Aden must pass. Saudi Arabia, the world's second-largest oil producer, has redirected its oil exports through this route after the Strait of Hormuz was effectively closed due to the Israel-Iran war. The Houthis' advance toward Bab al-Mandab potentially creates pressure at another vital shipping route on the opposite side of the Arabian Peninsula, even as they signal they do not intend to threaten international shipping broadly.
The fifth paragraph explains that Perim Island divides the Bab al-Mandab Strait and sits at the juncture where ships heading to the Suez Canal from the Gulf of Aden must pass. This satellite image shows the island's position and scale.
The fifth paragraph describes how Perim Island divides the Bab al-Mandab Strait, the southern gateway to a trade route linking Asia and Europe, and how Saudi Arabia has redirected oil exports through this route after the Strait of Hormuz closed. This map shows the island's strategic position between Yemen, Eritrea, and Djibouti.
