Yemen’s Houthi movement announced on Monday that it will impose a maritime blockade against Saudi Arabia, opening a new front that could expand the US-Iran conflict into global energy shipping routes beyond the Persian Gulf.
The announcement was reported to have initially pushed global oil prices higher before they later retreated amid hopes for a diplomatic breakthrough.
The developments were reported by Reuters on Monday, July 21, 2026.
According to Reuters, the Houthis said in a statement that they had declared “a maritime embargo against the criminal Saudi enemy, based on the principle of an eye for an eye, effective immediately,” in response to what they described as “the unjust blockade” imposed by Saudi Arabia on Yemen.
The move reportedly prompted an immediate response from the Saudi-led coalition in Yemen, which said it would respond with force and had begun implementing protective measures for its vessels passing through the Bab el-Mandeb Strait, a key export route for Saudi oil following the effective closure of the Strait of Hormuz.
The Bab el-Mandeb Strait is regarded as the main gateway to the Red Sea.
A complete closure of the strait is reported to have the potential to reduce global oil supplies by 7 percent, as much of Saudi Arabia’s oil exports would be unable to leave the region.
The disruption would reportedly compound the impact of the ongoing Gulf conflict, which has already reduced global oil shipments by 10 percent of worldwide supply.
Escalating Conflict, Casualties, and Diplomatic Efforts
The latest escalation reportedly follows one of the deadliest periods of the conflict for US forces.
The Pentagon reportedly identified two US soldiers who were killed when Iran attacked a US military base in Jordan on Friday.
In addition, unidentified human remains were reportedly found that may belong to a third soldier previously reported missing.
Separately, a fourth US service member was reportedly killed in northern Iraq during the controlled detonation of an Iranian one-way attack drone.
Trump reportedly defended the latest US strikes against Iran as a response honoring the American service members who had been killed.
“Every time Iran kills an American Soldier, they will pay for that killing many times over,” Trump wrote on Truth Social, as quoted in the report.
Meanwhile, diplomatic efforts were reportedly continuing.
A senior Iranian official reportedly told Reuters that Tehran had accepted a proposal from mediators for a 10-day ceasefire in an effort to preserve an interim agreement.
Iranian Interior Minister Eskandar Momeni reportedly asked Pakistan to continue its mediation efforts before arriving in Islamabad for further talks.
According to reports, two oil tankers exploded after attempting to pass through the strait via routes considered unsafe, based on a statement from the Islamic Revolutionary Guard Corps (IRGC).
In a separate incident, a vessel was reportedly struck by an unidentified projectile off the coast of Oman.
Explosions were also reportedly heard in several Iranian cities, including Tabriz, Chabahar, Konarak, Bandar Mahshahr, and Bandar Imam Khomeini.
One person was reportedly killed in southwestern Tabriz.
The IRGC reportedly launched ballistic missiles targeting US aircraft at Aqaba Airport in Jordan, as well as military assets in Kuwait, Ali Al-Salem Air Base, and positions in Syria.
Bahrain reportedly sounded warning sirens throughout Monday, while the Kuwaiti military reportedly intercepted Iranian drones early Tuesday morning.
On Monday, Hamas reportedly announced the appointment of chief negotiator Khalil Al-Hayya as the group’s overall leader, a move that one analyst said could signal a tougher stance toward calls for the organization to disarm.***
