The Pakistani Taliban claimed it carried out a suicide attack in Lahore to avenge a military operation in the northwest and vowed further deadly strikes, a spokesman said Thursday. "We claim responsibility for the Lahore suicide attack. It is revenge for the Swat military operation," Hakimullah Mehsud said from an undisclosed place, saying he was a spokesman for Pakistan Taliban chief Baitullah Mehsud. Baitullah Mehsud commands Tehreek-e-Taliban (TTP) and is Pakistan's most wanted militant with a five-million-dollar reward posted by the United States. "We were preparing to attack a target since the Swat operation started and with the grace of God we succeeded yesterday," said Hakimullah Mehsud.
