A Polish court has convicted and handed a suspended prison term to a former deputy head of government security over the 2010 plane crash that killed President Lech Kaczynski and 95 others.

The verdict Tuesday by a Warsaw court was the first prison term handed out over the April 10, 2010, crash of Poland's presidential plane in Smolensk, Russia, that killed all on board.

Pawel Bielawny was found guilty of neglecting his duties and exposing Kaczynski to danger and was given an 18-month suspended sentence and a 10,000-zloty (2,270-euro) fine.

Poland is currently governed by the conservative Law and Justice party led by Kaczynski's twin, Jaroslaw Kaczynski, who is intent on punishing those guilty of his brother's death.
