Afghanistan’s election commission has postponed Saturday’s elections in Kandahar province for a week.
It follows a deadly attack there that killed at least two senior provincial officials, including its powerful police chief.
Along with Mr Raziq, the province’s intelligence chief and two policemen were killed.
The condition of Kandahar’s governor, Zalmay Wesa, who was wounded in the attack, was shrouded in secrecy.
Mr Raziq’s funeral was being held on Friday in Kandahar’s holiest of shrines, Kherqa Mubarak, said to contain the cloak of Islam’s Prophet Mohammed.
The Taliban said on Thursday that Nato commander General Scott Miller had been targeted in the attack which he survived.
