Against the backdrop of tensions with Russia, a manoeuvre involving NATO troops has begun in western Ukraine.
About 6,000 soldiers from around a dozen countries will train for combat operations just 25 kilometres from the EU state of Poland, as the Ministry of Defence in Kiev announced on Monday.
Offensive and airborne operations will also be practised during the annual US-Ukrainian manoeuvre Rapid Trident until Friday of next week. The Bundeswehr has also sent an observer.
Ukraine has been training regularly with units from NATO countries since the 1990s.
Since 2019, the goal of joining the Western military alliance has been enshrined in the constitution.
In recent months, repeated military exercises by the West and Russia have caused tensions. In June, the Russian Black Sea Fleet said it had forced a British warship to change course away from the Crimean peninsula by firing warning shots and dropping bombs.
