Yemen's Iran-aligned Houthi movement reached the strategic island of Perim in the Bab el-Mandeb Strait on Friday, according to four Yemeni government sources, potentially tightening the group's grip on one of the world's most vital shipping routes and escalating threats to energy markets amid an widening Middle East war.
Two sources from the Saudi-backed, internationally recognized Yemeni government said its forces had withdrawn from Perim, and that the Houthis had also captured the mainland Red Sea coastal town of Dhubab, which faces the island.
If the Houthis gain full control of the Bab el-Mandeb Strait—situated on the opposite side of the Arabian Peninsula from the Strait of Hormuz—it could hand their backer Iran a critical advantage in its war with the United States, reducing supplies through a second major transit corridor and sending oil prices surging.
Saudi Arabia, the world's largest oil exporter, has relied on the Red Sea route since the Iran conflict effectively closed Hormuz, through which a fifth of global oil once flowed.
Global oil prices were on track to end the week above $100 a barrel for the first time since mid-May, though they dipped slightly on Friday after the Financial Times reported that Middle Eastern foreign ministers were attempting to broker a temporary deal to manage shipping through the Strait of Hormuz.
Yemeni Forces Vow Counteroffensive
Yemeni government forces indicated they would try to retake areas captured by Houthi militants during their lightning offensive this week along the Red Sea coastline.
They announced they would deploy weapons and aircraft to eliminate any movement of the "terrorist" Houthi militias in strategic areas, including the road leading to the coastal city of Mocha, which the militant group captured Thursday along with the Red Sea islands of Hanish.
Military spokesman Col. Majed al-Nazili called on civilians to avoid using the route between the city of Taiz and Mocha and to steer clear of equipment belonging to the Houthis—mountain fighters who withstood years of devastating Saudi airstrikes during Yemen's civil war.
Fighting between the Houthis and Yemeni government forces has intensified in recent days, with the Iran-aligned group shifting its focus to control over Yemen's long coastline instead of just the north and the country's most populous areas.
Reuters reported Thursday that the dramatic Houthi advance down Yemen's Red Sea coast this week came with direct guidance from Iran's Revolutionary Guards seeking to open a new front in Iran's war with the U.S., according to Yemeni government, Iranian and regional sources.
Iran told the Houthis last week to escalate their attacks on Saudi Arabia, a close U.S. ally, and promised more funding, weapons and senior officers to help them do so, two Iranian sources said.
While Iran describes the Houthis as an ally, it publicly denies giving them military direction, saying they are "not a proxy."
Trump Rejects Saudi Request for Strikes
Saudi Arabia has been bombing Houthi targets in Yemen but not the strategic areas the group has seized this week, raising questions about why Riyadh is not intervening more forcefully to help its Yemeni government allies as Iranian arms and advice helped the Houthis make significant gains.
Saudi Crown Prince Mohammed bin Salman called U.S. President Donald Trump twice on Thursday and urged him to launch strikes against the Houthis, Axios reported, citing two U.S. officials.
Trump rejected the request, and U.S. officials said the administration does not intend to take direct military action against the Houthis at this time, the report said.
According to Axios, the U.S. is increasingly concerned about the rapidly escalating conflict in Yemen and is stepping up support for Saudi Arabia while seeking to avoid direct military involvement.
Diplomatic Push on Hormuz
Gulf foreign ministers plan to meet their Iranian counterpart in a push by Oman and Iran to secure buy-in for a temporary deal to manage shipping through the Strait of Hormuz, the Financial Times reported Friday.
The gathering is scheduled for Monday in the Omani coastal city of Salalah, the report said, citing two people briefed on the matter.
