Scenes of devastation after plane carrying military munitions crashes in Greece, killing eight people
The plane had been transporting equipment including illuminating mortar shells and training shells to Bangladesh when it crashed near Eleftheroupoli in the northeastern Kavala region, the Serbian Minister of Defense Nebojša Stefanović said, according to Reuters.
Members of a mine clearing division have now entered the crash site and are investigating and identifying the munitions the plane was carrying, public broadcaster ERT reported, adding that the identification process will be followed by collection and demolition or on-site neutralization of the items as needed.
Smoke and intense heat, as well as a white substance found near the crash site, initially raised concerns over possible toxicity, Marios Apostolidis, a major general in the Greek fire brigade, said.
"The plane was already burning while it crashed. There was a big explosion, like a mushroom, like a nuclear bomb," one unnamed male resident told ERT.
"My stomach clenched, when I saw that mushroom," another resident said.
However, no dangerous substances have been found so far at the crash site, according to Greek Fire Service spokesman Ioannis Artopoios.
Greek authorities have recovered all eight bodies of the people who were on board, ERT reported Sunday.
The Antonov 12, which was operated by Ukrainian cargo airline Meridian, crashed shortly before 11 p.m. local time (4 p.m ET) Saturday, ERT reported.
It was traveling from Serbia to Bangladesh via Jordan when it crashed, Ukrainian Ministry of Foreign Affairs spokesperson Oleg Nikolenko said on Facebook Sunday. The cause of the accident is believed to be engine failure.
All eight crew members were Ukrainian citizens, Nikolenko added. He said an operational headquarters was set up by the Ukrainian consulate in Thessaloniki, where Ukrainian consular officers were working at the crash site with local rescue and law enforcement teams.
Following the crash, 15 firefighters with seven vehicles immediately went to the scene while additional firefighting forces followed including special units with two "special" vehicles for the collection of hazardous material, the ministry said, adding that the area of the crash was immediately cordoned off and a security perimeter was established.
There are currently 30 firefighters and "special forces" on the scene as well as police and other rescue teams, the Greek foreign ministry said in a statement.
Experts are also working to determine what the white substance is. Authorities have yet to recover the plane's flight recorder.
