Saudi Arabia is accused by the Houthis of carrying out 26 attacks in a single day.

The Houthi rebels in Yemen claim that in the last 24 hours, Saudi Arabia has launched 26 attacks against areas they control. The two sides are still exchanging gunfire as the conflict in Yemen intensifies.

The organization said on Friday that 300 Saudi attacks on Houthi-held territory had occurred in the last week alone, targeting locations throughout the regions it controls. In the al-Waziiyah district of Taiz province, one of several fronts where fighting has intensified this week, Yemen’s government, supported by Saudi Arabia, reported on Friday that its forces had killed thirty Houthi rebels and injured over sixty.

The conversation follows an increasingly intense conflict between the Houthi fighters and the government’s troops in Yemen.

Tens of thousands of people marched through Sanaa on Friday in support of the Houthis, who are backed by Iran, and in opposition to Saudi Arabia. The rebels have gained control over significant portions of Yemen’s Red Sea coast, including the vital Bab al-Mandeb Strait. At least five people, including three children, were killed earlier this week in the escalating attacks between the Houthi rebels and the Yemeni government, according to reports from both sides.

While Houthi-affiliated media reported deaths from Saudi attacks in Taiz and the town of Abs, Saudi Arabia said that one person was killed in the Taif governorate after a Houthi drone was intercepted. The Houthis’ ongoing attacks on Saudi Arabia were denounced by the United Nations Security Council (UNSC), which said that they had damaged energy infrastructure and killed civilians, including women and children.

In a statement released on Friday, UNSC members said: “The military escalation being carried out by the Houthis in Yemen, their continued attacks on Saudi Arabia, and the attacks and threats to international shipping in the Red Sea, along with the Houthis’ advance near the Bab al-Mandeb Strait, are all factors that threaten to widen the conflict, endanger maritime security and international trade, and undermine regional and international efforts to achieve peace in Yemen.”

Over the weekend, US officials met with Houthi delegates at the US embassy in Muscat, the capital of Oman, after the group’s swift territorial expansion sparked worries about shipping via Bab al-Mandeb, a crucial route for international trade. Washington apparently received assurances from the Houthis that ships unrelated to Saudi Arabia would not be targeted.

Riyadh has urged US President Donald Trump to take direct action against the Houthis, but Washington has so far refrained from doing so out of caution about creating a new front while also engaged in an expensive battle with Iran. As the situation in the region deteriorated, European Union foreign policy leader Kaja Kallas announced on Friday that the bloc’s Red Sea naval operation, Operation Aspides, had increased its alert level.
