At least 15 civilians were killed and 20 others injured in an explosion in central Afghanistan, the country's Interior Ministry said on Friday.
The incident took place in the restive Ghazni province on Friday morning when an explosive-laden motorcycle blew up inside a house in the Gilan district, said Tariq Arian, a ministry spokesman.
Arian said a gathering for the recitation of the holy Quran was underway at the time of the attack.
