Egyptian President Abdel Fattah el-Sisi has pledged to help defend Saudi Arabia if its security comes under threat amid escalating tensions with Yemen’s Houthi rebels. El-Sisi called for an emergency parliamentary session to authorise possible defensive military action, stressing that Cairo does not seek to attack anyone but will not allow Saudi Arabia’s stability to be compromised. The offer could add a new dimension to the conflict as Riyadh faces mounting security challenges and regional powers call for an end to the fighting.
