Islamabad, Jan 27 (Agencies): Banned Tehrik-e-Taliban warned that it would carry out more attacks against security and law enforcement personnel and also claimed responsibility for two suicide bombings targeting Shia processions in Karachi and Lahore.

Taliban spokesman Azam Tariq told reporters in the lawless North Waziristan tribal region on Wednesday that the two attacks on Tuesday were aimed against security personnel because "they serve US interests".

"The security forces will face attacks as they protect US interests in Pakistan. The state of lawlessness is so bad that President Asif Ali Zardari has obtained the services of US-based security agency Blackwater," Tariq said while talking to the reporters on phone from an undisclosed location.

"We will continue attacking the personnel of the security apparatus that are promoting US imperialism. They are creating hurdles for the soldiers of Islam. The personnel of the police and security forces are acting like the hirelings of the US and are destabilising Pakistan," he added.

Tariq claimed that Pakistan's top leadership "should keep in mind that they cannot protect themselves from Taliban attacks."

The country will be turned "into a citadel of Islam and secularism will be purged" from the land, he further claimed.

Sixteen people, including several policemen guarding the Shia processions, were killed and nearly 80 others injured in the two suicide attacks on Tuesday.
