Deadly blast hits boxing club in Shia neighbourhood of Afghan capital

The death toll from an explosion in a mostly Shia Muslim neighbourhood of Afghanistan's capital has increased to four, with seven people critically injured, a police spokesperson said.

The cause of the Thursday evening blast at a boxing club in Kabul is still not known. Khalid Zadran, a spokesman for the city's police chief, said the investigation into the blast is ongoing. He initially reported that two people died and nine were injured.

Video taken after the explosion shows part of a building with its windows blown out, flames billowing inside. Shattered glass and other debris are strewn across the street below.

The scale of the damage was clearer on Friday morning. There were craters in the ground and most of the club's interior has been gutted. Workers picked their way through boxing gloves and gym equipment on the blood-splattered floor.
