At least 15 military cadets have been killed in a suicide attack in Kabul, Afghan officials say, bringing the death toll of a week of attacks by various militant groups to around 200.
Defence ministry spokesman Dawlat Waziri said four others were wounded in the explosion at the gates of Marshal Fahim military academy, as they were leaving by minibus.
The bomber was on foot.
The Taliban have said they carried out the attack.
It was the second suicide attack in the city in 24 hours.
On Friday, 56 people were killed in a gun and suicide bomb attack at a Shia Muslim mosque, claimed by the Islamic State group.
The Sunni Muslim group did not provide evidence for its claim but it has attacked Shia mosques before.
Separately on Friday, 20 people were killed in an attack on a Sunni Muslim mosque in Ghor province. It is not clear who carried out that attack.
