HARI SREENIVASAN: Top U.S. officials offered new assessments of Iran's nuclear program. It came a day after the Islamic republic claimed major new achievements in producing its own nuclear fuel.
U.S. Defense Secretary Leon Panetta gave his assessment at a House hearing.
SECRETARY OF DEFENSE LEON PANETTA: The intelligence has been very clear on this. They continue to develop their enrichment capabilities.
But the intelligence doesn't show that they have made the decision to proceed with developing a nuclear weapon. That is the red line that would concern us and that would ensure that the international community, hopefully together, would respond.
HARI SREENIVASAN: Panetta repeated that all response options remain on the table to stop Iran from acquiring nuclear weapons.
At a Senate hearing, top intelligence officials said, if Iran is attacked, it might blockade the Strait of Hormuz, the gateway to the Persian Gulf oil states.

A top adviser said he would solicit that country's help in negotiating a peace agreement.
ISMAIL QASEMYAR, international relations adviser, Afghan High Peace Council: Hamid Karzai will ask the Pakistan head of state and the head of the government to cooperate to put positive and constructive pressure over the leadership of the Taliban to come close and to come together to start an intra-Afghan dialogue and a process, the negotiation.
HARI SREENIVASAN: A spokesman for the Taliban denied there had been any negotiations. He said the Taliban didn't talk with the Kabul government anywhere.
In Washington, State Department spokeswoman Victoria Nuland refused to confirm or deny either way.
VICTORIA NULAND, State Department spokeswoman: There are lots of Taliban saying lots of different things. So, again, we have said, and the secretary has made clear, this whole process is at a very preliminary stage.
We are still at the stage of trying to build the trust among the Afghans, so that they can sit in the room and have conversations. So that's the stage that we're at, and it's very, very preliminary.
HARI SREENIVASAN: The focus on possible peace talks has intensified, as U.S. and other NATO combat forces begin to withdraw from Afghanistan.
