Iran's Revolutionary Guard has shot down a US drone to send a “clear message” to the Trump administration after US secretary of state Mike Pompeo blamed the regime for an attack on two foreign oil tankers in the Strait of Hormuz last week.

Donald Trump has yet to address the incident but has been warned by Russian president Vladimir Putin that any war between the two nations would be a “disaster”. The Pentagon has meanwhile called the downing of the drone an “unprovoked attack” by Tehran in international airspace, although Iran says the drone crossed its border.

On Capitol Hill, the Senate is poised to vote on legislation to block the Trump administration from selling US-made weapons to Saudi Arabia and its allies. This follows a decision by the UK government to halt approvals for the sale of weapons that could be used in the conflict in Yemen after its processes were ruled unlawful by the Court of Appeal.
