About 70 university students in the Afghan capital held a rally against Pakistan, insisting Islamabad help investigate the assassination of former Afghan President Burhanuddin Rabbani.
Rabbani, who was trying to broker peace with the Taliban, was killed on Sept. 20.
Several Afghan officials have publicly accused Pakistan and its spy agency of supporting the militants who killed him.
Pakistan's government has said it is cooperating with the investigation into Rabbani's death and denied involvement in the killing.
At Thursday's march in Kabul, protester Mohammad Farad said the demonstrators want the Pakistan embassy in Kabul to be closed. They called on the United Nations to appoint a delegation to investigate Rabbani's killing.
