Yemen's Saudi-backed forces say they've secured the Bab al-Mandab Strait at the start of an offensive against the Houthis — though the Houthis deny it and claim strikes on Riyadh. Turkey and Pakistan

What happened: Yemeni pro-government forces backed by Saudi Arabia say they have secured the Bab al-Mandab Strait and captured the Red Sea city of Mokha, while the Houthis deny losing both. Key numbers: Saudi-led coalition says it destroyed 324 targets; Dhubab airport is 45km (27 miles) south; civil war began in 2014; at least 959 people killed. Why it matters: The Houthis struck Riyadh's airport and Aramco facilities in retaliation, and Turkey and Pakistan agreed to deploy forces to Saudi Arabia under the Mecca Joint Defence Agreement.
