Poland Investigates Blast as Tusk Warns Against Rushing to Blame RussiaPolish Prime Minister Donald Tusk said Warsaw would not draw premature conclusions after an unidentified object entered Polish airspace and exploded in the eastern part of the country, while also suggesting that Russia could potentially be involved. We want to be 100% certain about exactly what type of projectile was launched," the Polish prime minister said. The Polish Armed Forces reported that at 3:40 a.m. an unidentified object was detected moving westward through Polish airspace. Police responding to the scene discovered a crater between the villages of Tarnawa-Kolonia and Tokary, along with scattered fragments of an unidentified object. Russia Rejects AllegationsFollowing previous incidents, Kremlin spokesman Dmitry Peskov said that the European Union and NATO regularly accuse Russia of provocations without presenting sufficient evidence.
