Montenegro blocks 87 Serbian nationals from entering the country ahead of an EU summit with Western Balkans leaders, according to multiple reports. Authorities prevent the group—described as Serbian men—from crossing into Montenegro as part of heightened security measures tied to the regional meeting. The blocking is linked to assessments that the individuals pose a security threat for the summit and surrounding events. The reports cite the figure of 87 people barred from entry and describe the action as a pre-emptive step taken shortly before the gathering. The outlets do not provide further public detail on the specific reasons for each person’s threat assessment or on the legal process used to deny entry. The measures are portrayed as part of broader efforts by Montenegro to secure the summit involving European and regional leaders. The reports collectively present the same core facts: the number of people affected, their nationality, and that the decision is based on security concerns related to the EU-Western Balkans meeting.
