Mass protests erupted against Lukashenko last summer after he declared victory in a presidential election that the opposition said was rigged. The demonstrations have dwindled after the authorities launched a brutal crackdown, beating and arresting hundreds of activists.
"There's nothing more to wait for, we have to stop the terror once and for all," Tsikhanouskaya said in a statement on social media.
The aim of the new protests is new fair elections and the release of political prisoners.
As we reported earlier, Belarusian airline Belavia canceled all flights to Ukraine until August 25, 2021.
"Due to the ban of the Ukrainian authorities on Belavia flights, the airline is forced to cancel flights to/from Kyiv, Lviv, Odesa and Kharkiv from May 26 to August 25, 2021," the statement reads.
In addition, night flights B2 847 to Kyiv (departure time 22:40) and B2 833 to Odesa (departure time 23:40) were also canceled on May 25.
