The investigative committee, set up by the Polish government, has asked expert scientists at the British MoD’s Forensic Explosives Laboratory to help investigate the airline crash killing Polish President Lech Kaczynski, and 95 others on board in 2010.
Poland has stated that the incident is an “act of Russian aggression.”
The Rzeczpospolita, a leading Polish newspaper, said: “it has seen a report from Poland’s Central Forensic Laboratory and Central Bureau of Investigation saying experts found traces of TNT and nitroglycerine on numerous bits of the wrecked Tupolev Tu-154 including 30 seats and sections of the fuselage.” The official explanation at the time of the incident was “pilot error.”
Russia has refused to allow the wreckage to be investigated or transported back to Poland, and also denies any involvement.
“The murder of 96 people, including the president of Poland and other distinguished figures, is an unheard of crime,” said Jaroslaw Kaczynski, the bereaved twin brother of the late president and leader of Poland’s main opposition party Law and Justice, on Tuesday. “Anyone involved in this must bear the consequences of their actions, and this is what we will push for,” he continued, adding that his belief his brother died in an attack was unshaken.
The laboratory is renowned as one of the world’s leading counter-terrorism forensic expert labs, whose expertise is frequently drawn on for criminal prosecutions.
The laboratory investigated wreckage from the Lockerbie bombing, the Bali bombing, and the London 7/7 attacks. A spokesman for the MoD said: “The Forensic Explosives Laboratory (FEL) has agreed to the request from the Polish authorities to provide explosive trace analysis in relation to the Smolensk air disaster.”
