Durrani said the women were passengers on a bus boarded by armed men lying in wait in a sport utility vehicle Wednesday, The Nation reported Thursday.
The armed men kidnapped the two women and a guard, but released the guard after taking his weapon, Durrani said.
No one has claimed responsibility for the kidnapping and the government hasn't received a ransom demand, The Nation said.
Officials said the tourists held Czech Republic passports and entered Pakistan from Iran through the Taftan border crossing.
Durrani said police teams were searching for the women and their kidnappers.
