Afghan public health officials said 20 people were injured in the explosion that occurred outside the compound where Afghan President Ashraf Ghani was holding meetings on Sunday. He was not harmed.
The slain Sikhs were scheduled to meet Ghani.
"We are distressed and grieved at the loss of precious human lives. We express our deepest sympathies and heartfelt condolences to the families and friends of those who have lost their lives and pray for early recovery of the injured," Pakistan Foreign Ministry said.
The attack came a day after Ghani ordered Afghan security forces to resume offensive operations against the Taliban following the expiration of the government's 18-day ceasefire.
