US President Donald Trump has warned the US is "targeting" 52 Iranian sites and will strike "very fast and very hard" if Tehran hits Americans or US assets.

His comments followed the US assassination of Qasem Soleimani, a top Iranian general, in a drone strike.

Iran has vowed to avenge his killing.

Trump wrote on Twitter that Iran "is talking very boldly about targeting certain USA assets" in response to the general's death.

He said the US has identified 52 Iranian sites, some "at a very high level & important to Iran & the Iranian culture, and those targets, and Iran itself, WILL BE HIT VERY FAST AND VERY HARD" if Tehran strikes the US.

Trump added."The USA wants no more threats!"
