(Reuters) - Ukraine's Marta Kostyuk said on Friday it "hurts a lot" to see Russian flags at the Australian Open despite the ban on them and was surprised by the lapse in security that allowed spectators to display the flags in and around Melbourne Park.
Novak Djokovic's father Srdjan said earlier on Friday he would not attend his son's semi-final against Tommy Paul after a video emerged showing him posing at Melbourne Park with fans holding Russian flags.
