Kabul: A suicide bomber killed 63 people and wounded 182 in an attack on a wedding reception in the Afghan capital on Saturday night, the interior ministry said.

The Taliban denied responsibility for the blast at a west Kabul wedding hall, in a minority Shiite neighbourhood, packed with people celebrating a marriage.

Women and children were among the casualties, interior ministry spokesman Nasrat Rahimi said on Sunday.

More than 1000 people had been invited to the celebration on Saturday, local time, one witness said, as fears grew that it could be the deadliest attack in Kabul this year.
