KABUL, Feb. 6 (Xinhua) -- Three people, all women from the same family, were killed and another was injured after a gas cylinder exploded inside a house in eastern Afghanistan's Khost province on Thursday evening, provincial police spokesman Tahir Ehrar said Friday.
The ill-fated family was using a gas heater to warm their house in the chilly winter weather, but the cylinder of the heater exploded due to gas leakage, causing the fatalities, the official added.
A male member of the affected family who was badly injured has been taken to the hospital, the official added.
People in post-war Afghanistan, where there is no modern heating system, often use gas cylinders or wooden stoves to keep their houses warm during freezing winters, but deadly accidents sometimes occur due to gas leakage and explosion.
Several weeks ago, a gas cylinder blast left two women dead and injured two children in Spin Ghar district of eastern Nangarhar province. ■
