More than 1,000 troops from 15 NATO and non-NATO countries are taking part in a military exercise in Ukraine.
The “Rapid Trident” exercise is happening near Lviv on the Polish-Ukrainian border, around 1,000 miles from the conflict in east Ukraine.
Ukrainian army colonel, Oleksandr Syvak, said: “This year’s military exercise will concentrate on the particular aspects of the undeclared or “hybrid” war, which is happening in the east of Ukraine. This will be be taken into consideration during the military drill. The Ukrainian militaries will also share their experiences gained during the anti-terrorist operation”
Moscow has previously condemned what it calls NATO’s expansion in eastern Europe close to Russia’s borders.
In August, Ukraine’s prime minister said he would ask parliament to put the country on a path towards NATO membership.
At the weekend, the Ukrainian Defence Minister admitted NATO countries had begun arming his nation in the fight against the rebels – something NATO members had previously denied.
Euronews correspondent Mykhaylo Dubyak in Ukraine says: “In the Rapid Trident exercises, NATO and Ukrainian troops will train in how to react to an ambush and convoy operations, amongst other things. It will raise the combat capability of the Ukrainian army and may be used in operations in Donbas”
