Belpak / Beltelecom contact to address a BGP hijacking issue?

[sarah.nataf at gmail.com (Sarah Nataf)]

Hi all,

Does anyone have a technical or peering contact at Belpak / Beltelecom
(AS 66697) to address
an apparent netblock hijacking issue?

AS6697 is advertising the 2.2.2.0/24 address space which is under
AS3215 management.
We've tried to announce the same prefix but it's difficult to get the
traffic back!

No answer from people listed in the whois, no peeringDB information.
Any suggestions?

Thanks in advance,
