Three of Germany's major parties are holding gatherings on Saturday to firm up their programs and candidates ahead of the nationwide elections on February 23, following the collapse of Chancellor Olaf Scholz's three-party coalition, the DPA reported.
Organizers expect more than 10,000 people to attend demonstrations against the AfD. Participants from about 70 cities are due to arrive in more than 100 buses, they said.
Demonstrators also planned to block the access routes and entrances to the conference venue where the AfD rally is to be held.
While the situation remained calm in the morning, authorities anticipate the presence of violent protesters and have established a control zone within the town, located some 130 kilometers south of Berlin.
The AfD intends to adopt its election manifesto in Riesa and officially nominate party leader Alice Weidel as its chancellor candidate.
Saxony is one of the AfD's strongholds. In the last election, it won 24.6 % of the vote there, leaving the Christian Democratic Union (CDU), the traditional party of Germany’s conservatives, far behind with 17.2 %.
