Escalation in the Gulf area conflict certainly appeared overnight after Saudi Arabia accused Iran-backed Houthi rebels of targeting Mecca with a one-way attack drone, raising the risk of a deeper conflict as the kingdom's East-West pipeline was knocked offline last week.

Bloomberg quoted the Saudi-led coalition, which said an attack drone was intercepted heading toward Islam's holiest city and warned that protecting religious sites was a "red line."

"The security of the Two Holy Mosques and the pilgrims is a red line, and the Joint Forces Command of the coalition will not hesitate to take the necessary and deterrent measures against the Terrorist Houthi Militia," the kingdom said. 

Rep. Joe Wilson (R-S.C.) wrote on X, "If the Mecca Alliance means anything, then Turkiye and Pakistan must work with Saudi Arabia to destroy the foreign Houthi terrorists and liberate Yemen from Iran."
