Montenegrin police say they have arrested 20 people suspected of planning armed attacks after voting closes in parliamentary elections.
National police director Slavko Stojanovic said on October 16 that those arrested late on October 15 came from neighboring Serbia.
Stojanovic said the group planned to "pick up automatic weapons" to attack state institutions, police, and possibly state officials.
He did not provide further details.
