More than 20,000 soldiers and hundreds of tanks have taken part in a military parade in Poland. The parade commemorates Armed Forces Day and marks the 103rd anniversary of victory over the Soviet Union in the Battle of Warsaw. Poland is boosting its armed forces as war rages in neighbouring Ukraine and tension grows near its eastern border with Belarus, where Russia’s Wagner mercenary group has set up base.
