The Houthis announced a maritime blockade against Saudi Arabia on July 20.
The blockade was declared as retaliation for an airstrike on Sanaa's international airport on July 13.
The Houthi movement attributed the attack on the airport to Saudi Arabia.
The airstrike targeted the runway of Sanaa’s airport to prevent the landing of an Iranian aircraft carrying a Houthi delegation returning from Tehran after the funeral of Iran's Supreme Leader Ali Khamenei.
The Houthis declared the end of the ceasefire with Saudi Arabia that had been in effect since April 2022.
Saudi Arabia has led a coalition supporting Yemen’s internationally recognized government since 2015.
