Amid mass protests in Iran, Trump says Tehran 'wants to negotiate', meeting 'being set up'

US President Donald Trump said Sunday that Iran's leadership had called seeking "to negotiate" after his threats of military action amid mass anti-government protests in the Islamic republic.

"The leaders of Iran called" yesterday, Trump told reporters aboard Air Force One, adding that "a meeting is being set up... They want to negotiate."

However, Trump added that "we may have to act before a meeting."
