President Donald Trump said Saturday that military action against Iran was still an option for its downing of an unmanned USA military aircraft, but amid heightened tensions he dangled the prospect of eventually becoming an unlikely "best friend" of America's longtime Middle Eastern adversary.
President Donald Trump said Saturday he's still considering military action against Iran after it downed an unmanned USA military aircraft, saying the use of force is "always on the table until we get this solved".
The downing of the drone - which Iran insists violated its airspace, a claim Washington denies - has seen tensions spike after a series of attacks on tankers the United States has blamed on Tehran.
Iran recently announced it will soon exceed worldwide agreed limits on its nuclear programme.
Tensions have been escalating between the Iran and the United States after Mr Trump unilaterally pulled out of a 2015 nuclear deal aimed at curbing Iran's nuclear activities.

United States National Security Adviser John Bolton has warned Iran that it should not "mistake U.S. prudence and discretion for weakness", after President Donald Trump called off strikes against Iranian targets on Friday.

What happened with the drone?.
The downing of the United States drone came with Iran already accused by Washington of carrying out attacks on tankers in the congested shipping lanes out of the Gulf, charges Tehran denies.
Iran denies it attacked the tankers and says the drone was in its airspace.
Iranian Foreign Minister Javad Zarif on Saturday sent a series of tweets with maps created to show that the drone downed by Iran had been flying over its territorial waters, not global waters as the USA has said.
Amir Ali Hajizadeh, a high-ranking officer in the IRGC, said another military aircraft, carrying 35 passengers, had been flying close to the drone.
