London (CNN)The UK Royal Navy says it will now accompany British-flagged oil tankers through the Strait of Hormuz in the wake of Iran’s seizure of a ship last week.
The British Ministry of Defense (MoD) said the move was a response to “the heightened threat to commercial shipping in the Gulf,” and guidance from the Department for Transport, which advised Friday that ships should not sail through the area. “The Royal Navy has been tasked to accompany British-flagged ships through the Strait of Hormuz, either individually or in groups, should sufficient notice be given of their passage,” the MoD said. “Freedom of navigation is crucial for the global trading system and world economy, and we will do all we can to defend it,” the MoD added.
