NEW YORK, Dec 15 (Reuters) - Ukraine's former world number three Elina Svitolina said she fears people are forgetting about her compatriots, almost 10 months into Russia's ongoing invasion that has reduced cities to rubble.One of Ukraine's most celebrated athletes, she has added star power to a fundraising effort to supply electricity generators for Ukrainian hospitals as the invasion continues into the bitter winter months."We're here to do everything to tell people, to introduce them (to) what is really happening in Ukraine, because a lot of people come to me and ask, 'Is there still a war?''NOTHING DONE'Much of the sports world moved to ban athletes from Russia and Belarus - seen as a key staging area for the invasion - in February.Last week, the ATP fined Britain's Lawn Tennis Association (LTA) 820,000 pounds ($1 million) for banning male players from Russia and Belarus from this year's summer grasscourt events, months after the WTA slapped Wimbledon organisers and British tennis authorities with fines as well."
