沙特阿拉伯成为伊朗代理人冲突升级的最新焦点

也门胡塞武装与沙特阿拉伯之间的军事对抗出现重大升级。9月10日，胡塞武装攻占红海港口城市穆哈，并继续向曼德海峡方向推进。2这一事态发展打破了2022年4月以来的停火局面，标志着四年停火后也门冲突再度激化。2伊朗与沙特阿拉伯的代理人冲突升温，引发联合国安理会召开紧急会议。1巴基斯坦随之警告伊朗控制胡塞武装，沙特阿拉伯随即展开报复行动。1

此次军事冲突对全球能源供应链构成重大威胁。曼德海峡作为全球石油贸易的关键通道，约7%的全球石油贸易要从该海峡通过，2最窄处仅29公里。2若胡塞武装成功控制该水道，将对国际航运成本和油价造成严重冲击。早在7月，胡塞武装就已宣布对沙特实施海上封锁，2并于7月13日宣布打破停火平衡，向沙特南部发射导弹。2

The proxy conflict between Iran and Saudi Arabia has intensified significantly, with Yemen's Houthi-affiliated forces capturing the Red Sea port city of Mocha on September 10 and advancing toward the Strait of Mandeb 2. The escalation prompted the United Nations Security Council to convene an emergency session 1, while Pakistan issued warnings about Iranian control over the Houthi forces, leading Saudi Arabia to launch retaliatory operations 1.

This marks a critical shift in regional dynamics following four years of relative calm. The Houthis had announced an end to the ceasefire framework in July, when they fired missiles at southern Saudi Arabia 2, before ultimately seizing Mocha and pushing toward strategic chokepoints. The 2022 ceasefire agreement that had previously contained hostilities addressed only peripheral issues without resolving underlying disputes 2.

The geographic consequences carry global implications. The Strait of Mandeb, narrowing to just 29 kilometers at its tightest point, handles approximately 7 percent of worldwide oil trade 2. The Houthis declared a maritime blockade against Saudi Arabia as early as July 2, raising the prospect that further territorial gains could restrict shipping routes, dramatically increase transportation costs, and destabilize global energy supply chains if the strategic waterway becomes subject to control by hostile forces 2.
