There was no comment from Ghani or his embattled administration in Kabul. In a recorded message on Saturday, Ghani had told the nation he was consulting with both national and international players on the situation which he called an "imposed war".
The interior minister's pregnant assessment serves to negate Islamabad's outright rejection of allegations levelled by the United States and Afghanistan that Taliban terrorists use Pakistan's soil to direct and sustain their activities in Afghanistan.
The nation's capital and other urban areas have enjoyed a rare stretch of more than two months without the sorts of a large-scale bomb attack that frequently rock the city and cause mass causalities.
The Taliban in a statement has rejected any involvement in the attack and said they condemned incidents which target women and children.
The attack occurred two days after President Ashraf Ghani offered the Taliban a ceasefire during the holy month of Ramadan, which begins Monday.
On Thursday, several officials said a vital first step is an immediate reduction in violence, which has continued apace across Afghanistan even with various peace summits taking place.
At least 147 militants were injured. The US was supporting the Afghan government forces in conducting airstrikes tageting the Taliban.
