Moldovan officials have confiscated boxes of lists from a Russian jet in Chisinau reportedly signed by residents of the breakaway Transdniester region urging Russia to annex the territory.
The boxes were taken from the plane carrying Russian Deputy Prime Minister Dmitry Rogozin back to Moscow after his visit to Transdniester for Victory Day celebrations.
But Rogozin said most of the boxes arrived in Moscow.
He wrote on his Facebook page on May 11 that his delegation "brought home the message of Transdniestrians to the leadership of Russia."
Moldova's Foreign Ministry said the documents were seized to check "their lawfulness" and said the trip by Rogozin and his delegation of Duma deputies was marked by "provocative declarations."
Moldova's Russian-speaking Transdniester region has de facto independence and has asked Russia to annex it.
