Blood-soaked packages containing plucked-out animal eyes were sent to Ukrainian embassies across the world this week.
Ukraine's Foreign Ministry spokesperson Oleg Nikolenko wrote on Facebook of how the bloody letter bombs were found at high-profile targets, including Kyiv's embassies in Hungary, the Netherlands, Poland, Croatia, Italy and Austria.
The general consulates in Naples, Krakow, and Brno in the Czech Republic also received the grim mail.
