Leaders from Ukraine, Moldova and Georgia on Friday criticized the presence of Russian military in their countries saying they are a destabilizing factor in the three ex-Soviet republics.

Parliamentary speakers from the three countries issued a joint statement saying they were “profoundly concerned about Russian troops” in Moldova, “and Russian occupation and other forms of military intervention” in parts of Georgia and Ukraine, according to The Washington Post citing Associated Press.

The statement at the end of a one-day security conference in Moldova’s capital, Chisinau, also expressed displeasure at “coordinated foreign support for separatist movements,” and social media “operations” to discredit their pro-European governments.

It said the governments should enhance their capability to counter hybrid attacks and called on the European Union and U.S. to support them.
