Saudi Arabia accuses Houthis of targeting Mecca, calls it a 'red line'

• Saudi Arabia accused Yemen’s Houthis on Wednesday of launching an attack on the holy city of Mecca, which the Iran-backed rebels denied.
• Saudi Arabia, a US ally which has been the target of large-scale Houthi strikes since early September, declared Mecca a “red line” as it slid deeper into the new front of the Iran war.
