TUNIS, July 21. The Saudi-led coalition threatened Yemen's Ansar Allah movement (Houthis) with decisive action over its threats against ships in the Bab el-Mandeb Strait, coalition spokesman Maj. Gen. Turki al-Maliki said. According to the statement, the coalition command has begun implementing measures to protect commercial vessels transiting the Bab el-Mandeb Strait, and Houthi threats against passing ships will be met with a firm and decisive response, as they are regarded as a clear violation of international law and constitute acts of maritime piracy. Al-Maliki stressed that Houthi statements about the closure of Yemeni ports and airports are part of a disinformation campaign and an escalation against the Yemeni government and neighboring countries. The Houthis announced a maritime blockade of Saudi Arabia on Monday, saying the movement reserves the right to pursue comprehensive escalation in response to Riyadh's actions.
