A damaged Balticconnector gas pipeline that connects Finland and Estonia is pictured in this undated handout picture in the Baltic Sea.
Tallinn is investigating the cables incidents.
In the case of the Estonia-Finland cable damage, it is also focusing on the Hong Kong vessel, and on Thursday evening Kallas said all three incidents were likely connected.
The NewNew Polar Bear sailed over the Estonia-Sweden cable 133 kms (82 miles) before reaching the pipeline damage site.
It then crossed the Estonia-Finland cable 32 kms (20 miles) after the gas pipeline, according to MarineTraffic.
