Afghan President Ashraf Ghani says that the $500 million that Pakistan has pledged for reconstruction of Afghanistan would be better spent on fighting terrorism.
Speaking at an international conference on December 4, Ghani said that "some states provide sanctuary and tolerate" terrorist networks.
"As a Taliban figure said recently, if they had no sanctuary in Pakistan, they wouldn't last a month," Ghani said.
Ghani was speaking in the northern Indian city of Amritsar at the Heart of Asia conference aimed at stabilizing conflict-torn Afghanistan.
Ghani said his country "suffered the highest number of casualties last year. This is unacceptable."
According to the United Nations, there were 11,002 civilian casualties in total in the Afghan conflict last year, the highest level yet recorded in the country.
Afghan officials blame Pakistan-based militant groups for the escalating violence, including a series of deadly attacks in the capital, Kabul.
Pakistan says it is itself a victim of terrorism.
