As had been previously reported, a U. S.-born member of the terror group al-Qaida has been arrested in Pakistan but authorities said it was not Adam Gadahn.

The New York Times reported on Sunday that the operative, who was taken into custody in recent days in Karachi, was identified as Abu Yahya Mujahdeen Al-Adam. U. S. and Pakistani officials have said that the suspect was said to have been born in Pennsylvania and is suspected of commanding al-Qaida fighters in Afghanistan.

The Times further said that the arrest in Karachi follows the arrests of several Afghan al-Qaida senior leaders, including Mullah Abdul Ghani Baradar, described as the second-ranking leader in the Afghan Taliban.

Pakistani authorities have granted U. S. interrogators access to question Baradar but he has not provided "any actionable intelligence," a senior Obama administration official said, speaking on condition of anonymity.

The official further said," He's talking to us but we're still in the trust-building phase."

Gadahn was identified by FBI as part of an al-Qaida cell planning attacks designed to disrupt the presidential election in 2004, and put him on its most-wanted list.

According to CNN reports, a Los Angeles federal grand jury indicted him for treason in 2006. The first American to be so charged in almost 60 years, Gadahn faces the death penalty if convicted. The U. S. government is offering a reward of up to $1 million for his capture. (With Input from Agencies)
