Hundreds of protesters met again on Wednesday night to demonstrate against the construction of an Orthodox Church in a park in central Yekaterinburg.
Police could be seen standing hand in hand to protect a newly erected wall around the construction site after activists destroyed a metallic fence the night before.
Seven people where reportedly detained during Wednesday's protest in connection with the removal of the fence.
Wednesday was the third night of protests in a long-running dispute over the planned church. Demonstrators are demanding the preservation of the park and green spaces in the central Russian city.
St Catherine's Cathedral is supposed to be built by 2023 to mark the city's 300th anniversary.
Yevgeny Kuivashev, Governor of the Sverdlovsk Oblast, responded to the recent protests on his Instagram account.
"In this situation, one can understand believers, for whom the restoration of St. Catherine's Cathedral in the city is a question that rises from year to year and that still needs to be resolved. One can also understand protesters, for whom it is important to preserve every green tree in the centre of Yekaterinburg."
He called for dialogue between the church and protesters and invited them for talks. Despite negotiations, the authorities ruled that construction should go ahead. The mayor of the city has since promised to create another park at a place chosen together with activists.
