The incident took place near Tump town in Kech district of the province where militants and separatists have carried out brazen attacks on security and government officials and installations.
A senior police official in Quetta, Mir Zubair said the deputy commissioner and assistant commissioner of Kech district in Turbat were kidnapped after the gunmen overpowered their security men.
"They were returning to Turbat after a meeting with Iranian border officials at the border post near Turbat," he said.
The gunmen later allowed the staff and security personnel to go but have taken the two officials to an unknown location, he said.
Balochistan has snowballed into a lawless land with militants and separatists striking at will.
