Mourning continues after school massacre

Security in front of a school in northern Pakistan remains tight Friday, three days after dozens of children were killed in one of the bloodiest Taliban attacks the country has seen in years.

Flowers adorn the exterior of the military school where on Tuesday, Taliban gunman broke in and began shooting. At least 148 people were killed... 131 were students.

For those who did survive the thought of returning is terrifying.

Some student don't want to go to school, this boy said. They say the terrorists will come and kill us.

Although the country is used to militant attacks the outright assault on children prompted the government to promise tougher action on all militant factions.
