Poland invaded the Czech Republic last month, but says it was just a big misunderstanding

London (CNN)The Polish military has admitted it accidentally invaded the Czech Republic last month, but it insists its brief occupation of a small part of the country was simply a "misunderstanding."

Polish soldiers mistakenly crossed the country's border with Czech Republic in late May before setting up there, the Czech foreign ministry told CNN.
The soldiers, who had been guarding parts of the closed Polish-Czech border during the coronavirus pandemic, then started turning away Czech citizens who were attempting to visit a church in their own country.
    The snafu led the Czech embassy in Warsaw to take "immediate action" and notify its Polish counterpart, the Czech government told CNN, adding that Poland has still not formally explained why it mistakenly annexed its neighbor.
    "Our Polish counterparts unofficially assured us that this incident was merely a misunderstanding caused by the Polish military with no hostile intention, however, we are still expecting a formal statement," a Foreign Ministry spokesperson told CNN.
    "The Polish soldiers are no longer present and our citizens can again visit the site freely," the spokesperson added.
    "We are still waiting for the formal Polish statement," they repeated when asked how long Polish troops were in the country.
