President Bush kept up his pressure on Iran over its nuclear program on Wednesday, after a new intelligence report released yesterday said it had halted its activities four years ago.

Bush said Iran had not fully accounted for its nuclear activities and continued to block demands that it stop its uranium enrichment activities. Iran has maintained that such work is needed to develop nuclear energy for peaceful activities.

Bush added that Iran still posed a danger.

It is clear from the latest NIE (National Intelligence Estimate) that the Iranian government has more to explain about its nuclear intentions and past actions, especially the covert nuclear weapons program pursued into the fall of 2003 which the Iranian regime has yet to acknowledge, Bush said during a stop in Omaha.

The White House said Wednesday that it would continue to push for a third round of tougher sanctions on Iran.
