But during a speech in Kabul, Abdullah said he will demand new conditions for conducting the vote to prevent extensive fraud from occurring again.
ABDULLAH ABDULLAH, Afghan presidential candidate: When the people of Afghanistan participate in the elections, and hopefully in bigger numbers, they are taking a risk in some parts of the country. And they should be confident that that risk is worthwhile taking once again.
GWEN IFILL: The election drama in Afghanistan may have a direct impact on President Obama's decision on whether to order in more U.S. troops.

SEN. JOHN KERRY, D-Mass.: It's a two-week period. I think you really want to know that this has worked and you want to know what kind of government is coming out of it. So I think we -- you know, that's, again, why this is a very important period of time. And I would absolutely counsel the president to wait until the end of the runoff.
GWEN IFILL: Kerry has acted as a go-between with President Karzai in recent days and helped persuade him to accept the runoff.
There was also a new warning that Afghanistan's multibillion-dollar drug trade is doing damage worldwide. The smuggling of Afghan opium and heroin accounts for 90 percent of the world's supply.

MOHAMED ELBARADEI, director general, International Atomic Energy Agency: I very much hope that people see the big picture, see that this agreement could open the way for a complete normalization of relation between Iran and the international community. I would cross my finger that, by Friday, we should have an OK, an approval by all the parties concerned.
GWEN IFILL: Iran's chief delegate underlined that it's all subject to approval by leaders in Tehran. But he said, the proposal is on the right track.
ALI ASGHAR SOLTANIEH, Iranian ambassador to the IAEA: We are fully cooperating. We came to this meeting with the spirit of cooperation, flexibility.

GWEN IFILL: The other parties at the talks, the U.S., France, and Russia, also accepted the draft agreement for review. In Washington, Secretary of State Hillary Clinton urged Iran to act quickly on the plan.
A Massachusetts man was charged today with plotting to attack shopping malls in the U.S. and American troops in Iraq.

The fight between health insurance companies and congressional Democrats escalated today. Party leaders in the Senate announced they will try to kill the industry's exemption from antitrust laws. The House Judiciary Committee approved a similar plan.
