Afghan families have been burying their children who were killed in explosions outside a secondary school in the capital, Kabul, on Saturday.
Emotional scenes

More than 150 people were injured in the attack. Reports from Kabul say the city was busy with shoppers ahead of celebrations for Eid al-Fitr this coming week.
The Taliban announced on Sunday that they would observe a three-day ceasefire for the Muslim festival, which marks the end of the holy month of Ramadan.
The insurgents said they would be "halting all operations against the enemy to provide a peaceful and secure atmosphere".
The Afghan government is expected to reciprocate with a truce.
What's behind the increased violence? Afghanistan is seeing increasing violence as the US and Nato prepare to pull out all remaining forces from the country on 11 September.
On Saturday the US state department condemned "the barbarous attack" outside the school.

"We call for an immediate end to violence and the senseless targeting of innocent civilians," it said.
The European Union's mission in Afghanistan said on Twitter that "targeting primarily students in a girls' school, makes this an attack on the future of Afghanistan".

So many places in Afghanistan have endured so much pain, but the Dasht-e-Barchi neighbourhood in Kabul has suffered horrendously.
The neighbourhood is populated by members of Afghanistan's Hazara ethnic minority. As followers of Shia Islam, the Islamic State group (IS) views them as heretics, and has carried out a vicious campaign, attacking the softest of targets.
Dozens have been killed in bombings at sports halls, cultural centres, and places of education in particular.
Last year, and in 2018, IS suicide bombers struck tuition centres in the area killing more than 70 people. IS is not part of the peace talks between the Taliban and Afghan government, which in any case are currently stalled.
As of yet, there's been no claim for the attack on Saturday. However, IS continues to carry out assassinations and bombings in Kabul and the city of Jalalabad, despite having recently lost much of the territory it once controlled in the east of the country.
