The foreign secretary has said the UK will continue to provide defensive support against "reckless Iranian threats" but insisted it would not be drawn into a wider conflict in the Middle East.
Yvette Cooper was speaking after it emerged Tehran had targeted the joint US-UK military base in the Chagos Islands, with reports of two ballistic missiles being fired at the island of Diego Garcia.
Supporting UK interests included taking defensive action against ballistic missile threats, she added.
Cooper said the UK recognised "Iran's escalating threats to international shipping as well as their threats to our Gulf partners" and she reiterated it wanted to see a swift end to the conflict.
