Security forces have ended a gun and bomb attack on a university in north-west Pakistan in which 19 people were killed and 50 injured.
Four suspected attackers also died in a battle that lasted nearly three hours at Bacha Khan University in Charsadda.
There are conflicting reports about whether Pakistan Taliban militants carried out the assault.
The group killed 130 students at a school in the city of Peshawar, 50km (30 miles) from Charsadda, in 2014.
About 3,000 students are enrolled at Bacha Khan but hundreds of visitors were also expected on Wednesday for a poetry event.
