A man died from self-inflicted injuries after detonating explosives outside Brazil's Supreme Court on Wednesday, just days before the G20 Summit in Rio de Janeiro. The incident involved two explosions, with the first occurring in a parking area and the second at the court's entrance as the man attempted to enter. Brasilia Governor Celina Leao stated that no other individuals were harmed, and the Supreme Court judges were safely evacuated following the blasts. Authorities are investigating potential additional explosives linked to the deceased, as a timer was discovered at the scene. The explosions raised security concerns ahead of the gathering of global leaders, including U.S. President Joe Biden and Chinese President Xi Jinping. The Brazilian government has heightened security measures in response to the incident, which has been condemned as a deliberate attack on the judiciary.
