The Counter Terrorism Department (CTD) of Punjab Police arrested the IS members yesterday from the Lahore Cantonment area where they were planning to target some army buildings, a CTD spokesman said.
"CTD received intelligence reports that some terrorists were planning to attack sensitive government installations in the cantonment area and other parts of the city," he said.
The CTD team raided a house and arrested two suspected terrorists and shifted them to an investigation centre for interrogation.
The CTD official said both suspects belonged to banned IS group.
Last month, the CTD had arrested over a dozen members of IS from different parts of the Punjab province.
