Members of two infamous pro-Kremlin groups have stormed a human rights NGO’s seminar on how to deal with law enforcement at protests, saying they don’t want a repeat of the 2014 Ukrainian revolution in Russia. Two fringe nationalist groups called the National Liberation Movement (NOD) and SERB are known for attacks on opposition activists and art exhibits. The Sakharov Center’s seminar aimed to teach attendees about their legal rights during protests and how to defuse confrontations with riot police.

About a dozen NOD and SERB members armed with smartphone cameras disrupted the Sakharov Center conference less than 10 minutes after it started, footage from the Wednesday event showed. “We’re here because we don’t want Maidan in Russia,” one of the disruptors can be seen saying, referencing the 2014 wave of civil unrest in neighboring Ukraine that ousted the country’s pro-Russian president. “I want to walk the streets in peace. You have a designated protest spot, go and stand there and don’t raise hell,” she continued. The SERB and NOD members spilled a foul-smelling liquid and sang patriotic songs, the U.S.-funded Svoboda.org news website, a Russian-language affiliate of Radio Free Europe/Radio Liberty, reported. The event moved to a neighboring Sakharov Center facility following the disruption, the organization said. Both the seminar organizers and SERB activists have reportedly filed police complaints against each other.
