Afghanistan's Interior Minister Sirajuddin Haqqani warned Pakistan of 'accountability' for the deadly air strike on a Kabul drug rehabilitation centre.
At least 400 people were killed and 200 others wounded in the strike, with many victims buried in mass graves.
The Taliban government minister called those behind the bombing 'criminals' and vowed to seek justice.
Pakistan has denied targeting the centre, saying it carried out precision strikes on 'military installations and terrorist support infrastructure'.
