Journalists attacked at A-2355 base, Sevastopol, March 7, 2014
Russian troops attacked a military base in Crimea two days ago as can be read here: http://time.com/16294/russia-crimea-sevastopol/.
After failed negotiations for the whole base to surrender the Russians agreed to pull back. But within minutes masked Russian self defence people showed up, blocked the entrance with their cars and started attacking journalists.
As far as I know, this is the first attempt to take over a base and the first incident of soldiers (that still don’t admit being Russian) actually entering a military base.
