20 police recruits killed in suicide blast
A suicide bomber has struck outside the gates of a police academy in Afghanistan, killing at least 20 recruits.
A police officer said the attacker walked into a group of recruits waiting outside the police academy in Kabul and detonated his explosives-laden vest.
At least 25 other recruits were wounded.
No-one has claimed responsibility for the attack.
Earlier a massive truck bomb killed at least 15 people and wounded around 400 others in a government complex and a military base in a residential area of Kabul.
Police chief Abdul Rahman Rahimi said all of the victims in the first blast were civilians, including women and children.
The blast comes after the United Nations said on Wednesday that a growing number of women and children are getting hurt or killed in Afghanistan's war against the Taliban and other insurgents.
The total number of casualties in the almost 14-year conflict was up 1% in the first half of this year, compared to the same period last year, a new UN report said.
However, the number of women casualties rose by 23% and children by 13%.
