Poland 'invades' Czech Republic in 'misunderstanding'
Polish troops guarding the frontier as part of coronavirus measures took up positions by a chapel on the Czech side of the border. They apparently stayed there for several days. The soldiers prevented Czech visitors from accessing the site.
The incident took place in north-eastern Moravia, in an area that forms part of the historical land of Silesia - part of which extends into today's Czech Republic. Poland has described the incident as a mistake, although the Czech Foreign Ministry has said it has yet to receive an official explanation.
The chapel lies 30 metres inside Czech territory. The border is formed by a small stream.
A construction engineer overseeing repairs at the chapel had wanted to take photographs of the plaster. But he was turned away by Polish soldiers armed with machine guns, who had set up a roadblock on the path leading to the chapel.
At this point, it appears, the local Czech police force was contacted and the troops were ordered to leave.
