The assertion by Pakistan came as Prime Minister Nawaz Sharif chaired a special meeting of the National Security Committee of the Cabinet to review issues of national and regional security.
The forum strongly condemned the recent incident of terrorism in Kabul and resolved to remain steadfast and resolute in support of the Afghan people, according to a statement by the Prime Minister's Office.
"The participants expressed concern on the deteriorating security situation in Afghanistan and strongly rejected the baseless allegations on Pakistan in that context," the statement said.
The Afghan intelligence service, the National Directorate of Security (NDS), had said early findings showed that the Haqqani network with the assistance of the ISI carried out the attack yesterday in Kabul.
