An explosion has hit the Afghan capital Kabul near the parliament building, on a day NATO forces formally hand over security to national forces.
Tuesday's blast occurred at around 9am local time in an area called Karta-e Seh, a Kabul police source said.
It came as hundreds of local and international officials gathered on the capital's outskirts ahead of a ceremony to mark the beginning of the final phase of security transition to Afghan forces across the nation.
