At least six people were killed and 24 wounded on Tuesday by two bomb blasts that struck a boys’ school in a Shiite Hazara neighbourhood of the Afghan capital, police and hospital staff said. The number of attacks in Afghanistan has significantly declined since the Taliban ousted the US-backed government in August, but the jihadist Islamic State group has claimed several since then. Several bodies were strewn outside the gate of the school in the densely populated neighbourhood in Kabul, alongside patches of blood, burnt books and school bags, according to images posted on social media.
