According to Reuters, Russia is negotiating with the Yemeni Houthis through Iran about the transfer of long-range anti-ship P-800 Onyx missiles.
On September 24, Houthis managed to hit a US Navy supply ship for the first time. Russian P-800 Onyx missiles will help them sink even behemoth American aircraft carriers easily.
According to Yakov Kedmi Telegram channel, the P-800 missiles will be programmed by Russian officers, just as American officers program US-made ATACMS missiles for strikes on Russian targets.
