Iran struck a bulk carrier 23 nautical miles north-east of Doha on Sunday 10 May, hours after the first Qatari LNG tanker since 28 February transited the strait of Hormuz, while Qatar's Prime Minister Mohammed bin Abdulrahman Al Thani was simultaneously meeting Marco Rubio and JD Vance in Washington to discuss de-escalation.
