Polish and Nato troops hold war games in response to Russia-Belarus manoeuvres
Thousands of Polish and Nato troops have launched major defensive exercises in Poland's north following war games recently held by neighbouring Russia and Belarus.
The Dragon-17 exercise involves some 17,000 troops and some 3,500 units of equipment and runs until September 29.
For the first time the bi-annual drill is joined by Poland's new defence force, the Territorial Defence Forces, which train civilian volunteers to support the regular troops.
Deputy Defence Minister Michal Dworczyk is expected to visit the exercise on Thursday.
He has said the drills test defensive operation between Polish troops and those deployed in Poland by Nato and by the US in response to the region's concerns over Russia's military activity.
Russia and Belarus wrapped up war games on Wednesday.
