Iran has imposed sanctions on 15 American companies over their alleged support for Israel, terrorism and repression in the region.

A Foreign Ministry statement carried by the state-run IRNA news agency Sunday said the companies are barred from any agreements with Iranian firms and that former and current directors will not be eligible for visas.

The move is seen as a response to U.S. sanctions placed on dozens of Iranian entities in February following an Iranian missile test. Iran's sanctions are unlikely to have much impact as none of the targeted U.S. companies are known to do business in Iran.

Iran's sanctions target US firms that provide arms and equipment to Israel "for use against the Palestinians", IRNA said.

"All transactions with these firms are forbidden, their assets will be seized and their officials will not be able to obtain a visa," it added.

The companies include Bent Tal, United Technologies Products. ITT Corporation, Raytheon, Magnum Research Inc., Oshkosh Corporation, Kahr Arms and Elbit Systems.

The list also included Re/Max Real Estate, which Tehran accuses of "buying and selling homes in settlements located in the occupied territories".

Tensions have mounted between Tehran and Washington since U.S. President Donald Trump took office in January.

On Friday, Washington announced sanctions against foreign firms and individuals over allegedly collaborating with the weapons program of Iran and North Korea.

Trump has repeatedly criticized a July 2015 deal between Iran and world powers that saw the Islamic republic curb its nuclear program in exchange for sanctions relief.

Washington last month imposed new sanctions on individuals and companies supporting Iran's ballistic missile program and on its elite Revolutionary Guards.

U.S .lawmakers are now seeking to further increase pressure, proposing a new law that would see Iran's Revolutionary Guards listed as a terrorist organization.
