Two school girls have been k!lled with five other children wounded when gunmen opened fire on a school bus in Pakistan on Thursday.
According to a Police official, Usman Haider, the attack occurred in Attock, a town in Punjab’s central province, while the children were on their way to classes in the morning.
Haider added that the dead and wounded children were between the ages of five and 10. 
He said the motive of the crime was not immediately known, but preliminary investigation pointed towards a feud between two families.
“We are also looking into the possibility of terrorism,” the officer said.
Pakistani President Asif Ali Zardari has condemned the incident and ordered police to apprehend the gunmen, his office said in a statement.
