Blasts rock Yemen's capital as Houthis vow to retaliate

Key points

• Houthi-run media say a Saudi-led coalition has attacked a fuel depot in Yemen's capital, Sanaa. The Houthis have vowed to strike Saudi airports and oil refineries in response.
• The oil company said its storage tanks were empty, and it was not immediately clear which facilities were hit. The attacks follow a missile and drone strike on Riyadh's airport on Saturday that killed at least 13 people.
