Iranian Foreign Minister Javad Zarif on Saturday warned that sending U.S. military forces to the Middle East would heighten tension in the Gulf region.

“These actions are also a threat to global peace and stability,” Zarif said in statements cited by the official IRNA news agency.

“Such dangerous moves should be encountered,” he said. “The U.S. is leveling baseless allegations against Iran to justify its aggressive policy towards the Islamic Republic.”

“Such a step would only heighten tensions in the Persian Gulf region,” Zarif warned.

On Friday, CNN reported that U.S. President Donald Trump approved sending some 1,500 U.S. troops to the Middle East in a “mostly protective” effort on deterring “Iranian threats”.

Tensions between Washington and Tehran have mounted steadily since Trump unilaterally withdrew the U.S. from a landmark nuclear agreement between Iran and the P5+1 group of nations (the five permanent UN Security Council members plus Germany).

The Trump administration has also re-imposed sanctions on Iran’s banking and energy sectors, while Iran has threatened to close the strategic Strait of Hormuz to U.S. oil shipments.
