"Accordingly, we regard raising any flag (by the Kurds) other than that of the Iraqi flag in Kirkuk is a move which escalates tensions," Qasemi was quoted as saying.
The move can waste the energy of the Iraqi government and undermine the Arab country's anti-terror campaign, he added.
Iraqi lawmakers reportedly passed a bill on Saturday to prohibit hoisting the flag of the Kurdistan autonomous region in Kirkuk, days after the Kirkuk Provincial Council decided to raise the Kurdish flag next to the Iraqi national flag in front of some buildings.
