(TELEGRAPH) — Saudi Arabia has intercepted a rocket fired by rebel Houthi fighters in Yemen, who declared a “new chapter” in its confrontation with the kingdom.

The Volcano 2-H ballistic missiles was aimed at the al-Yamma royal palace in Riyadh, but was stopped by Saudi’s air defences.

Reporters heard a blast and saw a plume of smoke rising above the Saudi capital near the palace, where King Salman chairs weekly government meetings and hosts foreign dignitaries.
