Boris Johnson on oil tanker attack: 'Iran should face up to the consequences of what they have done'
Boris Johnson has said Iran "should face the consequences of what they have done" after the country was blamed for an attack on an oil tanker which left a British national dead.
Asked if the UK would consider military action as part of its response to the attack, the prime minister said: "I think that Iran should face up to the consequences of what they have done, accept the attribution that the Foreign Secretary has made.
"This was clearly an unacceptable and outrageous attack on commercial shipping, a UK national died. It is absolutely vital that Iran and every other country respects the freedoms of navigation around the world, and the UK will continue to insist on that."
Iran's ambassador to the UK was earlier summoned to the Foreign Office over the attack on oil tanker Mercer Street last Thursday.
The country was warned it must "immediately cease actions that risk international peace and security" after the UK said it is highly likely Iran was behind the drone strike on the vessel off the coast of Oman.
Middle East minister James Cleverly told the Iranian diplomat that Tehran must "immediately cease actions that risk international peace and security".
Earlier on Monday minister Matt Warman told ITV News it was "right" for the UK to blame Iran and welcomed a joint condemnation made by the US and Israel.
'This is the right response', says minister
The strike on the tanker, Mercer Street, on Thursday night was the first known fatal attack after years of assaults on commercial shipping in the region linked to tensions between Israel and Iran.
British maritime security firm Ambrey said the attack, which saw a hole blasted through the vessel's bridge, killed one of its employees aboard.
The Mercer Street is managed by London-based Zodiac Maritime, part of Israeli billionaire Eyal Ofer's Zodiac Group.
The Foreign Office said the drone assault followed similar attacks on three other Israeli-linked ships in the region since February.
A Foreign Office spokesman said: "The Iranian ambassador to the UK, Mohsen Baharvand, was summoned today to the Foreign, Commonwealth & Development Office by the minister for the Middle East, James Cleverly, in response to the unlawful attack committed on MV Mercer Street on 29 July.
"Minister Cleverly reiterated that Iran must immediately cease actions that risk international peace and security, and reinforced that vessels must be allowed to navigate freely in accordance with international law."
Foreign Secretary Dominic Raab has promised to work with allies on a "concerted response" to Iran following the attack, which also killed a Romanian.
US Secretary of State Antony Blinken said he is confident that Iran carried out the attack using explosive drones - "a lethal capability it is increasingly employing throughout the region".
Tehran has denied responsibility, accusing Israel of making baseless accusations against Iran.
