Poland opens new probe into plane crash that killed president in Russia

Poland’s government has opened a new investigation into the 2010 plane crash in Russia that killed president Lech Kaczynski, the twin brother of the chairman of the country’s ruling party.

The development could exacerbate Poland’s already strained relations with Russia and is likely to deepen the ideological divide within Poland between supporters of the conservative and pro-Catholic government and a segment of society that is liberal and secular.
