KRAKOW, Poland, Safar 14, 1438, Nov 14, 2016, SPA -- Polish prosecutors on Monday began the exhumation of President Lech Kaczynski, who died in a plane crash in Russia in 2010, to examine his remains as part of an investigation into the tragedy likely to deepen political divisions in Poland, Reuters reported. The crash near Smolensk in western Russia, which killed 96 people including Kaczynski's wife, top army brass and the central bank governor, has become one of the most fraught public issues in Poland, with some claiming foul play. An inquiry by Poland's previous, centrist government ruled pilot error caused the government's Soviet-made TU-154 to crash into the ground in heavy fog during an attempt to land. But Kaczynski's twin brother Jaroslaw, whose nationalist-minded Law and Justice party (PiS) unseated the centrists in an election last year, has said an onboard explosion could have caused the crash. Prosecutors want to determine whether there was no mix-up of remains during burial, as well as whether damage to the bodies had been described correctly in previous inquiries, arguing that Russia's refusal to return the plane's wreckage was a critical obstacle. -- SPA 22:21 LOCAL TIME 19:21 GMT www.spa.gov.sa/w269516
