The hacker group Anonymous has made personal data of a thousand police officers in Belarus (what we called Belarus until recently) public.
The group shared the data in response to police brutality in government protests in the country.
Anonymous threatened to leak more data through Telegram messaging service if police continue to arrest protesters.
Belarusian police have arrested thousands of protesters in recent weeks.
The units that perform during the demonstrations often wear balaclavas and large helmets.
Anonymous states in the message on Telegram that: "No one will remain anonymous, not even with a balaclava."
The government wants to track down and punish those responsible for the leak.
According to a spokesman for the Ministry of the Interior, it will be difficult to find out who is behind the leak.
Since the elections of August 9, there has been unrest in Belarus.
Protesters don't trust the election results.
President Lukashenko won the election with 80 percent of the vote.
The Organization for Security and Co-operation in Europe (OSCE) has started an investigation into possible human rights violations.
It looks at possible violations in the prosecution of opposition members, journalists and activists.
Why do we call Belarus Belarus from now on?
Since independence in 1991, after the collapse of the Soviet Union, the country has been officially called the Republic of Belarus.
That name is therefore used in official texts.
Belarus does more justice to what the population calls the country itself.
Some Belarusians take offense at the name Belarus because of the association with Russia.
Previously, we used the established name Belarus, because it is more recognizable to many readers.
