The Pakistan Cricket Board has written a letter of complaint to the International Cricket Council over hats worn by the Indian team.
India's players wore military-style camouflage caps in Friday's third one-day international against Australia in Ranchi.
India say they wore the caps in tribute to the country's armed forces following the killing of at least 40 paramilitaries in a suicide attack in the disputed region of Kashmir on 14 February.
The attack was claimed by the Pakistan-based Jaish-e-Mohammad militant group.
PCB chairman Essan Mani said he has written to the ICC to protest against the caps, saying India had "tried to use cricket for politics".
