Lithuania, Latvia and Estonia imposed travel bans on Belarusian President Alexander Lukashenko and 29 Belarusian officials on Monday amid protests against the country’s August 9 presidential election.

The sanctions target officials they accuse of having a role in vote-rigging and in violence against protesters since the election.

“We said that we need peaceful dialogue and agreement between the regime and society, but we see that the regime is not ready for that,” Lithuanian President Gitanas Nauseda said. “We see that we need to move forward and to show an example to other countries.”

“We have said before that Belarus will need to take adequate measures to respond to the initiators of these steps. This will be done,” Anatoly Glaz, spokesman of the Belarusian Foreign Ministry, told RIA news agency.
