Mike Pompeo: US 'deeply concerned' over Iran 'threats'

US President Donald Trump's new secretary of state issued a strong warning to Iran during his Middle East tour.

Mike Pompeo criticised Tehran, saying it is "destablising the whole region".

Pompeo's trip included visits to Saudi Arabia and Israel and comes as Trump edges closer to a decision on whether to pull out of the 2015 Iran nuclear deal.
