Four militants stormed into Bacha Khan University in Charsadda, Pakistan, killing 20 people and injuring 60 others, NBC News reported.
The gunmen, using heavy fog as cover, killed some of the victims execution-style with a shot to the head after striking classrooms and dorms, police and witnesses said.
Regional police chief Saeed Wazir told NBC News the attack appeared to be well-planned because “they knew where to go and they knew who to go for.”
All four were wearing explosive vests but only one managed to detonate his, police said. The others died in a shootout with Pakistani military. At least two appeared to be teenagers.
Bacha Khan University is named after Khan Abdul Ghaffar Khan, a progressive politician and champion of women’s rights. Wednesday is the 28th anniversary of his death.
