"The windows have been buckled, and the walls have fallen in... looking at the extend of the damage, I can understand why [the toll] may possibly rise," Aljazeera.net reports.
It was also reported, there was no immediate claim of responsibility.However, Taliban and al-Qaida-linked extremists have carried out a two-year campaign of suicide bombings and commando raids that have killed 2,250 people.
A spike in attacks since October 5 which have left more than 170 people dead has underlined the scale of the insurgency that authorities are trying to halt.
The Taliban last week staged an audacious attack on army headquarters in Rawalpindi, the garrison town adjoining Islamabad, with 23 people killed and 39 hostages freed by troops.
Five UN World Food Programme workers were also killed earlier this month when a suicide bomber walked into their office in Islamabad and blew himself, dressed in military uniform.
Authorities believe many of the bombings and suicide attacks in Pakistan, as well as attacks in the West, are being planned in the semi-autonomous tribal area of South Waziristan where the army launched its offensive on Saturday, Times of India reports.
