Though recent casualty reports cite improvised explosive devices as the leading cause of civilian deaths, they are extremely rare in Kabul.
On Saturday afternoon, a bomb attached to a police vehicle in the Pol-e Kheshti area of Kabul was reported to have killed one member of the Afghan National Police and wounded another.
