Islamabad , Pakistan ( CNN ) -- Pakistani Taliban leader Hakimullah Mehsud is dead , three Taliban sources and a government official said Tuesday . There were conflicting reports about where Mehsud died . The government official told CNN Mehsud died as a result of the January 14 attack in North Waziristan . He was seriously injured , and was moved to the Orakzai region , where he died and was buried more than a week ago , the official said , citing information from local pro-government militias . Other sources said Mehsud died near the city of Multan in central Pakistan while on his way to a treatment center in Karachi . Authorities have been looking into reports that Mehsud died after being wounded last month in a drone attack . Word of his death contradicts a statement by a Taliban spokesman last week that Mehsud was alive and in hiding . Also last week , a Pakistani news outlet reported that Mehsud had been killed . State broadcaster PTV reported that Mehsud was wounded in a drone attack this month , died and was buried . The drone attack occurred at a madrassa , or religious school , said Pakistani intelligence and local officials in North Waziristan . The school had been converted into a training camp for militants , the officials said . That attack came a few days after Mehsud appeared in a video released by the Pakistani Taliban . In it , he sits next to Humam Khalil Abu-Mulal al-Balawi , the man thought to be the suicide bomber who killed seven CIA officers and consultants and a Jordanian army captain at a base in eastern Afghanistan on December 30 . The Pakistani Taliban claimed responsibility for that attack . It was carried out to avenge the death of Mehsud 's predecessor , Baitullah Mehsud , who died in a suspected U.S. drone strike last year , according to al Qaeda 's commander of operations in Afghanistan , Mustafa Abu Yazid . Baitullah Mehsud and Hakimullah Mehsud are from the same tribe , not the same family . The U.S. military routinely offers no comment on reported attacks by drones , or unmanned aircraft . But the United States is the only country operating in the region known to have the ability to launch missiles from remote-controlled aircraft . Journalist Nasir Dawar contributed to this report .
