Houthis escalate with Red Sea blockade amid raised stakes in Yemen conflict

What happened

Al Jazeera Yemen reports that the Houthi rebel group, also known as Ansar Allah, has declared a maritime siege on all shipping heading to Saudi Arabia and has attacked several Saudi tankers in the Red Sea. This marks a significant escalation in the Yemen civil war as the Bab al-Mandeb Strait—a strategic chokepoint linking the Red Sea and the Gulf of Aden—comes under threat, impacting key global trade and energy supply routes.

Outside Brief is treating this as a source-led account. Any disputed responsibility, casualty figure, battlefield claim or single-source assertion should be treated as unconfirmed/hearsay unless confirmed by another reliable source or a named official. The Houthis, who took control of Yemen’s capital Sanaa in 2014 and receive backing from Iran, have indicated a willingness to disrupt this crucial maritime passage, which serves both European energy supplies and Saudi imports. Their announcement emerges alongside heightened regional tensions driven by the US-Iran conflict following US and Israeli strikes on Iran in February 2026.

According to the Yemeni internationally recognised government, an air strike was conducted on Sanaa airport on Monday to stop an Iranian plane from landing in the Houthi-held capital. The Houthis blamed Saudi Arabia for this attack. In retaliation, the Houthis launched missile attacks into Saudi territory before declaring their naval blockade, demonstrating a shift from traditional land-focused confrontations to maritime threats.

Known from the source

• Houthis have declared a maritime siege on all shipping to Saudi Arabia.
• Houthis have attacked several Saudi tankers in the Red Sea.
• The Bab al-Mandeb Strait is a strategic waterway linking the Red Sea and Gulf of Aden.
• Houthis control Yemen’s capital, Sanaa, since 2014.
• Yemen’s internationally recognised government conducted an air strike on Sanaa airport to stop an Iranian plane landing, a claim from the government side.

What remains unclear

Meanwhile, the government side has reorganised its military forces, consolidating command structures and increasing troop numbers to roughly 400,000 personnel, with deployments concentrated in government-held areas including Marib and Taiz. Additional government-aligned forces such as the Giants Brigades and Guardians of the Republic account for thousands more fighters. However, the Houthis retain control over large northwest regions including Sanaa, maintaining a complex military balance.

What remains unclear: Confirm whether the central claim is corroborated; until then treat it as unconfirmed/hearsay. Details and independent verification of the air strike on Sanaa airport. Evidence of the maritime siege’s enforcement and impact on shipping traffic. Verification of missile strikes by Houthis against Saudi Arabia and any resulting casualties.
