A Podgorica court on April 13 said lawmakers Andrija Mandic and Milan Knezevic of the Democratic Front, two Russians, nine Serbian citizens, and one other Montenegrin were charged with "creating a criminal organization."
Montenegrin officials allege that Serbian and Russian nationalists plotted to take over parliament during the October 2016 parliamentary elections, assassinate then-Prime Minister Milo Djukanovic, and install a pro-Russia leadership to halt Montenegro's bid to join NATO.
Prosecutors said the Russians, identified as Eduard Shishmakov and Vladimir Popov, were based in Serbia and were allowed by authorities there to return to Russia. They remain at large.
Montenegro's special prosecutor has said "Russian state bodies" were involved in the alleged coup, something Russia denies.
On Oct. 16, 2016, the day of the parliamentary elections in Montenegro, a group of 20 people used firearms in attempt to seize the parliament building and announce the victory of certain political forces.
According to prosecutor Milivoje Katnic, the coup was plotted by Russian nationalists who intended, among other things, to kill Prime Minister Milo Djukanovic.
