The Afghan leader told an worldwide peace conference in the capital on Tuesday that the attack, which took place at a highly fortified area of the capital, targeted "the entire diplomatic community".
The death toll from the devastating attack has jumped to more than 150 people, while over 300 wounded were brought to hospitals, many with burns and amputations, Ghani told the conference.
Kabul has been on edge since the massive truck bomb on Wednesday last week ripped through the city's highly fortified diplomatic quarter, home to the presidential palace and a host of foreign embassies. "So many Afghans were killed and injured it can not be treated as business as usual".
Ghani paid specific tribute to the 13 policemen who were killed by the explosion as they attempted to stop the truck.
AS anger is growing in Kabul and elsewhere in Afghanistan over utter failure of those at the helm of affairs to improve security, some elements in Afghan Government and outside, in their bid to divert attention of the people from domestic failures, have started blame game against Pakistan.
After the blast Wednesday, protesters, many of them members of the powerful northern Jamiat-i-Islami party, took to the streets, accusing government officials of cooperating with terrorists.
A spokesperson for the Afghan ministry initially told NBC News in the aftermath of the blast that at least 80 people had been killed, although that figure has now risen significantly.
Afghan President Ashraf Ghani said neighboring Pakistan has instigated an "undeclared war of aggression" against his nation after repeated bombings in Kabul in the past week, including the deadliest attack on the capital in 16 years.More news: Texas governor calls for session that could include bathroom bill

Representatives of around two dozen countries will attend the meeting, which aims to build worldwide support on ways to restore security in the conflict-torn country, the government said on Monday. Afghan officials allege that Taliban insurgents are using sanctuaries on Pakistani soil to wage the insurgency.
"Even if Russian Federation and others want to hold peace meetings, their agendas would have to be in accordance with the Kabul Process".
However, one of the main stakeholders in the war - the Afghan Taliban - is not present at the conference that hopes to achieve a lasting peace process with the armed group. Afghanistan also wants to build strong political and economic ties with its neighbors.
"He hopes that would really lay the ground work for other to come in and join the peace process".
NAN reports that security has steadily worsened since 2014 and the end of the main North Atlantic Treaty Organisation combat mission, which at its peak featured more than 100,000 American troops and tens of thousands more from alliance partners like Britain.
The push for a new peace process comes as U.S. President Donald Trump has yet to announce his plans for the region, with at least 8,400 American troops training Afghan forces and conducting counterterrorism operations.
Previous global efforts to bring the Taliban to the negotiating table have failed, but diplomats in Kabul hailed Tuesday's conference as a stepping stone to peace.
