(Reuters) - Pakistan's Taliban insurgents claimed responsibility for an attack on a security academy at Karachi's airport on Tuesday, less than 48 hours after an all-night siege by Taliban gunmen at Pakistan's busiest airport that killed more than 30 people.
"We accept responsibility for another successful attack against the government," Pakistani Taliban spokesman Shahidullah Shahid told Reuters. "We are successfully achieving all our targets and we will go on carrying on many more such attacks."
