USAir Group Inc said a U.S. DistrictCourt in Pittsburgh issued a temporary restraining order to
prevent Trans World Airlines Inc from buying additional USAir
shares.
    USAir said the order was issued in response to its suit,
charging TWA chairman Carl Icahn and TWA violated federal laws
and made misleading statements.
    TWA last week said it owned 15 pct of USAir's shares. It
also offered to buy the company for 52 dlrs a share cash or 1.4
billion dlrs.
