KYIV, Dec 18 - The largest Ukrainian telecom operator Kyivstar expects to achieve complete stabilization in the provision of services by the end of the week, after which it will announce a compensation program, company president Oleksandr Komarov said in a video message on Facebook.

“We have achieved significant progress after the world’s largest Russian hacker attack on civilian infrastructure. Voice services operate without restrictions, both in Ukraine and abroad. Mobile Internet services operate with speed limits and so far only in Ukraine,” he said.
