"Russia’s foreign minister warned that any actions seen as
endangering a Russianpeacekeeping contingent in a separatist region of
Moldova would be considered as an attack on Russia itself.

affairs school underlined concerns that Moldova’s Transnistria region,

Russia has stationed peacekeepers there since the 1992 end of a
three-month war that left Transnistria outside Moldovan control. Russian
forces also guard a large ammunition dump in the region." TheHill
