KABUL, Afghanistan: An explosion in downtown Kabul on Monday killed at least seven people and wounded about a dozen more, according to an Italian medical charity running a surgical care facility in the city. The reasons for the blast were not immediately clear. The explosion appeared to have hit a restaurant in the Shahr-e-Naw district of the Afghan capital. In the first few minutes after the blast, a police spokesman, Khalid Zadran, had identified the facility affected as a hotel.
