British maritime security firm Ambrey receives reports of suspicious activity near Yemen's Mokha

British maritime security firm Ambrey received on Tuesday reports of suspicious activity from two merchant vessels southwest of Yemen's Mokha, though no damage was reported. A tanker either saw flares or missile trails while a bulk carrier detected three small vessels approximately 1 mile in the direction of their port quarter.

The bulk carrier reported seeing two missiles fired from the direction of the boats and one unmanned aerial vehicle flying ahead of the vessel, Ambrey added in an advisory note.
