Iran targets certain USA assets

President Donald Trump on Sunday has warned Iran saying if it strikes any Americans or American assets, the US has "targeted 52 Iranian sites" and it "will be hit very fast and very hard." "Let this serve as a warning that if Iran strikes any Americans or American assets, we have targeted 52 Iranian sites (representing 52 American hostages taken by Iran many yrs ago), some at a very high level and important to Iran and Iranian culture, will be hit very fast and hard," Trump wrote on Twitter.
