Yemeni forces have seized a US-made REMUS 600 autonomous underwater vehicle belonging to the Saudi Navy, according to pro-Houthi sources. The vehicle was seized inside the Yemeni territorial waters in the Red Sea.
The REMUS 600 is often used to detect sea mines and to conduct reconnaissance in coast waters.
