London, July 11, 2019, SPA -- The British government has called on vessels flying the flag of the United Kingdom to be cautious as they cross Iranian waters. The British Ministry of Transport has increased the readiness of these ships to the maximum degree after reports that Iranian Revolutionary Guard boats yesterday intercepted one of the British tankers, advising those ships to move during daylight and increase the speed of crossing over normal while sailing across the Strait of Hormuz. -- SPA 21:59 LOCAL TIME 18:59 GMT 0022 www.spa.gov.sa/w1135442
