At least 19 people have been killed and dozens wounded in a gun attack on a university in Pakistan.
Four armed men in suicide vests opened fire at the Bacha Khan University campus in Charsadda, in the north-west of the country.
Local media reports the attack appeared to have begun at a hostel for male students, although the victims include both men and women. The gunmen climbed over a wall to reach the building at around 9.30am local time (4.30am GMT), before firing indiscriminately on students and staff.
