PODGORICA (Reuters) - The Kremlin has a secret list of Montenegrin officials that are banned from entering Russia, due to the small Adriatic republic's participation in Western sanctions over Ukraine, the country's Prime Minister Dusko Markovic said on Wednesday.

Earlier this week, Montenegro's foreign ministry summoned the Russian ambassador in Podgorica to protest over the brief detention of a deputy from the ruling Democratic Party of Socialists (DPS) at a Moscow airport.
