(Agencies) - Britain has concluded that Iran was responsible for attacks on oil facilities in Saudi Arabia, U.K. Prime Minister Boris Johnson said Sunday. He said the U.K. would consider taking part in a U.S.-led military effort to bolster the Gulf kingdom's defenses.
But the Conservative prime minister also said the U.K. would work with allies to "de-escalate" Middle East tensions that have soared since the Sept. 14 attack on the world's largest oil processor and an oil field.
A U.K. official told The Associated Press that a claim of responsibility for the attacks by Iran-allied Houthi rebels in Yemen was "implausible." He said remnants of Iran-made cruise missiles were found at the attack site, and "the sophistication points very, very firmly to Iranian involvement." He spoke on the condition of anonymity to discuss intelligence findings.
The official did not say whether Britain believed the attack was launched from Iranian soil.
Iran denies responsibility and has warned any retaliatory attack targeting it will result in an "all-out war."
