UN Security Council: Theresa May defends Brexit vote at General Assembly as Trump chairs meeting

Donald Trump has chairing a United Nations Security Council meeting - a first for the US president.

It means that most of the attention that would have been focused on events at the General Assembly - where UK Prime Minister Theresa May would later defend the Brexit vote - was instead focused on the UN's most powerful body, where the US currently holds the rotating presidency.

While the meeting of the council addressed the issue of nonproliferation of nuclear, chemical and biological weapons, Mr Trump himself used the platform to attack Iran and accuse China - but not Russia - of meddling in 2018 midterm elections.

On Tuesday, during an unabashedly "America First" speech, Mr Trump said Iranian leaders "sow chaos, death and destruction" and "spread mayhem across the Middle East and far beyond." His national security adviser, John Bolton, also warned that there would be "hell to pay" if Tehran crossed the US, its allies or their partners.

Iranian President Hassan Rouhani responded by accusing the Mr Trump administration of violating the rules of international law and "state obligations" by withdrawing from the 2015 nuclear deal that Iran signed with the US and five other major powers.

Mr Rouhani did not to attend the Security Council meeting that. The council is populated by five permanent members -- the US, China, Russia, Britain and France -- and 10 other member states, who occupy a council seat for two-year terms. Iran is not among them.
