TEHRAN - Iran's Foreign Ministry Spokesman Ramin Mehmanparast said Tuesday that Iran's "peaceful" nuclear program is progressing and will accelerate by installing new centrifuges.

The spokesman made the remarks in his weekly press briefing.

Asked about the media reports on the "slow speed" of Iran's nuclear program and the ongoing scheduled "test of new generation of advanced enriching centrifuges," Mehmanparast said Iran's " peaceful" nuclear program is advancing and by "installing new centrifuges this will be accelerated with higher quality."

This is a proof for the "successful implementation of Iran's nuclear activities," said Mehmanparast.

The issue has been announced to the International Atomic Energy Agency (IAEA) and they have complete supervision on the Iranian nuclear activities, said the Iranian official.
