No confirming word on Zawahri, which makes me think it is a false report. But there is this, from AP:
KARACHI, Pakistan (AP) “” Security forces following up on a raid that killed a top al-Qaeda fugitive arrested four more suspected extremists Monday, and Pakistan’s president predicted the investigation would lead to more high-profile militants.
President Gen. Pervez Musharraf lauded the killing of Amjad Hussain Farooqi, who died in a four-hour gunbattle Sunday after vowing never to surrender. Farooqi was wanted for his alleged role in the 2002 beheading of Wall Street Journal reporter Daniel Pearl and in two assassination attempts on the Pakistani president in December 2003. Three other Pakistanis, one of them an Islamic cleric, were arrested in the raid.
“We eliminated one of the very major sources of terrorist attacks. He was not only involved on attacks on me but also on attacks elsewhere in the country. So a very big terrorist has been eliminated,” Musharraf told reporters in the Netherlands while traveling home from New York.
“Together with him there have been some other arrests and we will get a lot of useful information leading to further arrests and eliminations, I am very sure,” Musharraf added. He did not identify those who had been captured.
