Item 5.          Other Events

         On January 13, 1999, Global TeleSystems Group, Inc., through its
subsidiary GTS Translantic Holdings Ltd., entered into an agreement with FLAG
Telecom to form a 50/50 joint venture that will build and operate a
transoceanic fiber optic link between Europe and the United States to be known
as FLAG Atlantic-1.  FLAG Atlantic-1's link is designed to carry voice,
high-speed data and video traffic at speeds of 1.28 terabits per second, a
25-fold increase over current transatlantic cable systems.  The joint venture
will also provide backhaul links from the European landing points of the
transoceanic link to Paris and London.  By interconnecting to FLAG Atlantic-1,
GTS Carrier Services and its subsidiary HER will be able to provide their
carrier and Internet service provider customers with high-capacity cable access
from major European cities to New York City.  GTS's investment in FLAG
Atlantic-1 is designed to enable it to participate in the growth opportunity
represented by the rapid increase in demand by business customers for Internet
Protocol-based telecommunications services.  The high-capacity fiber optic link
will be based on synchronous digital hierarchy and use dense wave division
multiplexing technology.  FLAG Atlantic-1 is expected to being offering service
by the end of  the year 2000.  The project is subject to financing, the
execution of related agreements and other conditions.  Additional information
regarding GTS's financial and other participation in the joint venture is set
forth in the two press releases which are included as exhibits to this Report.
