A journalistic investigation attributes the series of parcel fires to Russian military intelligence. The publication cites the Lithuanian prosecutor's office, which named three suspects publicly, a joint investigation team coordinated by Eurojust, and unnamed security sources. I have not read those documents, so the grade stays journalistic rather than official. No verdict has been reached on the parcel explosions themselves.
