"Iran is playing with fire - they don't appreciate how kind President Obama was to them. Not me!" Trump said in a tweet.
Earlier in another tweet, Trump claimed that Obama bailed Iran out from its economic crisis.
"Iran was on its last legs and ready to collapse until the US came along and gave it a life-line in the form of the Iran Deal: USD 150 billion," he told his 23.5 million followers.
Early this week, the US National Security Advisor Gen (rtd) Michael Flynn put Iran on notice and said that the United States would respond appropriately against the alleged destabilising behavior of Iran.
