WASHINGTON - Three U.S. soldiers were arrested for allegedly plotting a new attack on Fort Hood, the Texas base where a former Army psychiatrist went on a deadly rampage in 2009, a report said Thursday.

Fox News, citing an unidentified army source, said that a U.S. soldier who had gone missing without official permission was captured off the base and is being held by police in Killeen, Texas.

The television network said that two more soldiers were arrested when they were found with weapons and explosives. It said it had the men's names but was withholding them.

A U.S. Army spokesman at the base could not immediately be reached for comment early Thursday.

On November 9, 2009, Major Nidal Hasan, an Army psychiatrist who was set to deploy to Afghanistan, allegedly shot dead 12 soldiers and one civilian before police bullets wounded him.

Hasan, who goes on trial on March 5, faces the death penalty if convicted. Investigators allege that Hasan had contact with key al-Qaida cleric Anwar al-Awlaqi, a U.S. citizen who is at large in Yemen.
