Poland's PM Donald Tusk said the unknown object that crashed into a field in eastern Poland on Thursday, leaving a 33-foot-wide crater, may have been a Russian missile. However, he said authorities wanted to be "100% certain" about who launched the missile. Tusk said he was in contact with fellow European leaders before heading to the scene of the incident.
