(The Strategist) – The blood stains on the classroom walls couldn’t be washed away following the Taliban attack on the middle school in Postak Bazaar village in Afghanistan. ‘We had to chip it away from the wall with an axe,’ a school official told Human Rights Watch. But the blood wasn’t that of the school’s students. It was that of seven members of the Afghan National Police, a counter-insurgency force that had set up their military base inside the school. That attack was in 2010. After the Taliban retook the area, their fighters too slept in the school.
