Britain will face "repercussions" over the seizure of an Iranian supertanker, Iran’s president has said.
Hassan Rouhani was quoted by the official IRNA news agency as calling the seizure "mean and wrong" during a Cabinet meeting.
He warns London: "You are an initiator of insecurity and you will understand its repercussions," without elaborating.
Last week, authorities in Gibraltar intercepted an Iranian supertanker that was believed to be breaching European Union sanctions by carrying a shipment of Tehran’s crude oil to war-ravaged Syria.
The marines worked alongside authorities to detain the 1,082-foot oil tanker, thought to be heading to the Banyas refinery in Syria.
The tanker’s detention comes at a particularly sensitive time as tensions between the US and Iran grow over the unravelling of a 2015 nuclear deal, which President Donald Trump withdrew from last year.
