U.S. President Donald Trump has tweeted on Friday a clear warning to Iran, accusing the middle-eastern country of "playing with fire" over Iran's latest ballistic missile test. Referring to the previous administration of Barack Obama, Mr Trump added that the Iranian government didn't appreciate how "kind" that the US had been to them.
Trump was referring to the nuclear deal struck with the US and other world powers in 2015 where Iran's nuclear capability was reduced in return for a loosening of sanctions. Mr Trump said that he would not follow a similar path. 
The comment appeared to prompt a quick response from Mohammad Javad Zarif, Iran's foreign minister.
"Iran unmoved by threats as we derive security from our people. Will never initiate war, but we can only rely on our own means of defence," Zarif wrote also on Twitter.
Also on Friday, Iran said it had barred a US wrestling team from participating in the Freestyle World Cup competition in retaliation for an executive order by Trump banning visas for Iranians, Iran's state television reported.
