Ships operating in the Middle East Gulf have been put on high alert following the suspected drone attack on a Zodiac Maritime-controlled tanker which killed two crew.

The 49,992-dwt Mercer Street (built 2013) was attacked on 30 July off the coast of Oman. The attack is suspected to have been made by an unmanned aerial vehicle (UAV), with the Israeli, US and UK governments pointing the finger at Iran.
