Pakistani Taliban leader Hakimullah Mehsud has appeared in a new video issued months after his reported death, vowing revenge attacks on the United States. In the footage apparently recorded in April, Hakimullah Mehsud referred to reports of his death as propaganda. <br/><br/>The new nine-minute video, which was broadcast on Pakistani TV today, showed Mr. Mehsud sat between two armed, masked men. <br/><br/>Mehsud threatened to retaliate against the United States within a month for the killing of Islamist militant leaders. <br/><br/>Mehsud was reported to have been killed in a US drone strike in northwestern Pakistan on January 14, but Pakistani intelligence officials were quoted as saying last week that he had survived the attack.
