Russia sent over two dozen horses to North Korea on Wednesday in the first known rail shipment between the countries in nearly three years, Primorsky Krai’s veterinary customs agency said in a press release.

A train carrying 30 gray Orlov Trotter horses departed from the Russian border town of Khasan into North Korea after the horses (5 stallions, 25 mares) were quarantined in Suzdal, near Moscow. After an unspecified period of time, the animals were shipped to the DPRK border “in three specially equipped car carriers,” the veterinary customs agency states.
