Senior officials from Europe were traveling by train after attending a security conference. They had been joined by former prime ministers Boris Johnson and Carl Bildt. The group departed a station earlier than planned, according to Ukraine's state rail operator.

A drone attack occurred shortly after the diplomatic train left the station. The target of the attack is believed to have been the train carrying the visiting officials.

Further details about the incident are available, including a video shared by Carl Bildt showing the attack.
