A Taliban spokesman in Afghanistan rejected reports that the son of the founder of the powerful Haqqani militant network has been killed.

Zabiullah Mujahid said in an email sent to reporters late Saturday that Haqqani is alive and in good health in Afghanistan."A number of media have reported that Badruddin Haqqani has been killed. We would like to inform all media that this rumor is not correct," Mujahid said in the email.Pakistan is investigating whether the son of the founder of the powerful Haqqani militant network, which has been blamed for high-profile attacks and kidnappings in Afghanistan, was killed in a U.S. drone strike this week, officials said Saturday.

Pakistani intelligence officials have also said they are 90 percent certain he was killed in an American missile strike Tuesday in the North Waziristan region. They said their information was based on reports received from their agents in the field but acknowledged they haven't spoken to anyone who has seen the body.The U.S. has long viewed the Haqqani network as one of the biggest threats to U.S. and NATO forces in Afghanistan as well as the country's long term stability. The group has shown little interest in negotiating with the Washington, and has pulled off some of the highest-profile and most complex attacks in Afghanistan, although not necessarily the most deadly.
