Pakistani Taliban leader Hakimullah Mehsud has vowed in a new video to attack the United States within a month in revenge for the death of other militant leaders.
"The time is very near when our fedayeen (devotees) will attack the American states in the major cities," SITE quoted Mehsud as saying.
He said Tehreek-e-Taliban Pakistan (TTP) would attack the United States "for having martyred many of our great Muslim leaders, including Baitullah Mehsud and many respected brothers from Al-Qaeda".
Mehsud was believed to have been killed in a US drone strike in northwestern Pakistan in January, but very recently Pakistani intelligence officials announced that he had survived the attack.
Officials said at the time that he was killed in a US missile attack along with at least 10 suspected militants. He was seriously wounded when missiles fired by a US drone struck his vehicle in the Shktai area on the border between South and North Waziristan.
Mehsud is the leader of the terrorist group, Tehreek-e-Taliban, which has been involved in attacks across Pakistan and Afghanistan. He has also been blamed for bombing of a Central Intelligence Agency base in eastern Afghanistan in December that killed seven Americans.
Meanwhile, another video allegedly from TTP group also claims that it was behind an attempted car bombing in New York's Times Square at the weekend, but the authorities in New York rejected the claim.
"There is no evidence that this is tied in with Al-Qaeda or any other big terrorist organization," New York Mayor Michael Bloomberg declared.
The Pakistani government has announced cash rewards (about 590,000 dollars) for the arrest or information leading to Mehsud's capture, dead or alive
