Australia's Usman Khawaja was reprimanded by the International Cricket Council (ICC) on Thursday for sporting a black armband after the global body's rules prevented him from wearing shoes with messages of support for Gaza in a Test against Pakistan. "Usman displayed a personal message (armband) during the first test match against Pakistan without seeking the prior approval of Cricket Australia and the ICC to display it, as required in the regulations for personal messages," an ICC spokesperson said.
