TEHRAN, July 28 (Xinhua) -- Iran's Foreign Ministry on Friday slammed Washington's threats and pressures pertaining to Tehran's recent successful launch of a satellite carrier.

The launch of satellite carrier is "Iran's inalienable right" and in compliance with its international obligations, Iran's Foreign Ministry Spokesman Baharm Qasemi said, according to the ministry's website.

The Islamic republic will not wait for the permission of others for its scientific research and activities, said Qasemi.

The U.S. opposition to Tehran's successful launch of rocket is an indication of Washington's "intervention approach in the internal affairs of other countries," Qasemi said.

The United States should stop its "hostile attitude" towards Iran, he said, adding that "instead of accusing Iran of unfounded charges, the United States is better to quit repetitive violation of international regulations and give up unbounded sales of fatal weapons which have targeted the peace in the region."

The United States imposed on Friday new ballistic missile sanctions on Iran in response to what it called Tehran's "continued provocative actions" including a recent rocket launch, said U.S. Treasury Department.

The sanctions targeted six Iran-based subsidiaries of Shahid Hemmat Industrial Group, a company central to Iran's ballistic missile program, said the treasury department in a statement.

Iran launched on Thursday a space vehicle which used technologies "closely related to those of an intercontinental ballistic missile," representing a "threatening step by Iran," said the statement.
