Al Jazeera: Attacks that have continued across Pakistani towns and cities are being blamed on Tehreek e-Taliban, Pakistan's Taliban.
However, the group has issued its first video statement denying involvement in targeting civilians and has blamed external forces for at least two recent blasts.
Azam Tariq, a spokesman of the Tehreek e-Taliban, posted the video statement on YouTube on Monday.
The message refers to a bombing at the Islamic University in Islamabad, which the spokesman said was orchestrated to prepare the ground for a military operation in South Waziristan, a stronghold for Pakistan's Taliban fighters.
He also said his group had no role in the bomb blast in a Peshawar market that killed at least 100 people as well as an attack in Charsada, a town located in Pakistan's North West Frontier Province.
Tariq said Taliban attacks never aimed to target civilians, but that the explosions were linked to Blackwater activities in the country.
