According to two sources who spoke to Fox News, the U.S. is sending military assets to the Middle East as tensions remain high between the White House and Iran’s regime – which has endured days of massive anti-government protests.

It is not yet clear whether the carrier is the USS Abraham Lincoln, currently operating in the South China Sea, or one of two carriers that departed Norfolk and San Diego earlier this week. Transit to the region is expected to take at least a week.

Military assets from air, land and sea are expected to flow into the region in the coming days and weeks to provide the president with military options should he decide to carry out strikes against Iran, sources told Fox.

They said U.S. military planners are preparing a range of options that would depend on how Iran’s regime acts in coming days.

The president has said he would act against Iran if the killing of protesters there continued, though on Wednesday he said the killings in Iran were “stopping.”

Trump added that Iran had also called off scheduled executions of demonstrators it has detained.
