Targeting Bin Laden's Caves

Dec. 5 -- As U.S. forces bombed caves where Osama bin Laden is believed to be hiding, President Bush told ABCNEWS the United States was "tightening the noose" on the suspected terrorist mastermind.

Bush, in his first television interview since the Sept. 11 terror attacks on America, told Barbara Walters that U.S. forces may strike other countries in the war against terrorism. The exclusive interview airs tonight on 20/20.

"We're making progress. We're making it harder for him to find sanctuary. We are closing down caves, we are getting more and more of the territories under control of our friends and allies, and therefore, we have a better chance of spotting him in person," Bush said in the ABCNEWS interview.

"We're tightening the noose on Osama bin Laden," he said. Asked if he would prefer to see bin Laden brought in "dead or alive" — a term Bush himself phrased after Sept. 11 — the president said he did not care.

Meanwhile, in Germany, rival factions signed a deal creating an interim cabinet to govern Afghanistan.

Heading for the Caves

On the ground in Afghanistan, U.S. military and opposition troops are preparing to attack a cave complex in eastern Afghanistan. A senior Northern Alliance commander told ABCNEWS he was preparing about 1,500 of his troops, along with U.S. special forces on the ground, to attack the Tora Bora cave complex near the eastern city of Jalalabad.

According to Arab television network Al-Jazeera, U.S. air strikes on the caves and tunnels have killed the wife and four children of bin Laden's top lieutenant, Egyptian exile Ayman al-Zawahiri.

A U.S. official said that report appears credible. However, al-Zawahiri himself is believed to have escaped injury.

Although the Pentagon has no confirmation of bin Laden's whereabouts, the Tora Bora complex is a key focus in U.S. attempts to capture the prime suspect in the Sept. 11 attacks and other leaders of his al Qaeda network.

In addition, a CIA-back opposition group from Jalalabad is said to be taking 1,000 fighters into the Tora Bora mountains to hunt for bin Laden. Some CIA personnel may accompany the group.
