Police officers briefly detain dozens of demonstrators in the Armenian capital, Yerevan, as protesters march against government plans to concede land to the country's historic foe, Azerbaijan. Large numbers of police surround the demonstration, led by Armenian archbishop Bagrat Galstanyan. "By gathering in Republic Square with other people and by committing other acts of civil disobedience, we want to remove (Prime Minister) Pashinyan from office," says 64-year-old protester Yeghisabeth Hovhanisyan.
