An object that crashed into a field in eastern Poland overnight on July 30 was probably a Russian missile, Polish Prime Minister Donald Tusk said. The missile threat made for an "extremely tough night" for Polish air defense, observation and threat detection systems, the country's defense minister Wladyslav Kosiniak-Kamysz said on social media the following morning. Polish Prime Minister Donald Tusk is traveling to the site, a Polish government spokesperson said on July 30. The reported incursion is not the first time Russian mass attacks on Ukraine have tested Polish air defenses. In another incident on Nov. 15, 2022, a missile flew into Polish territory during a Russian mass strike, killing two civilians.
