Organisers of Berlin's New Year's Eve celebrations are to set up a "safe zone" for women for the first time.
The new security measures planned for the Brandenburg Gate party come amid concerns about sexual assaults.
A large number of assaults and robberies targeting women at Cologne's New Year's Eve celebrations two years ago horrified Germany.
Hundreds of women reported being attacked by gangs of men with migrant backgrounds.
The events in Cologne heightened tensions in the country over the large influx of refugees and migrants - 1.1m people arrived in Germany in 2015, some, but by no means all, fleeing violence in Syria and Iraq.
