According to the Daily Mail:
A Bulgarian politician today survived an extraordinary assassination attempt when a man stormed the stage and held a gun to his head as he was giving a speech.
Fortunately for Ahmed Dogan, leader of the Movement for Rights and Freedoms, the weapon misfired giving him time to react and hit the would-be assassin's hand out of the way.
Before he could attempt a second shot the unidentified suspect was tackled to the ground by security guards and delegates attending the conference in Sofia.
Police said they arrested a 25-year-old man from the Black Sea town of Burgas who was also carrying two knives.
