A man with explosives died in an apparent suicide attempt after trying to enter Brazil's Supreme Court in Brasília on Wednesday, resulting in two explosions and the evacuation of court justices and staff. The incident has heightened security concerns ahead of the upcoming G20 summit in Rio de Janeiro and a subsequent state visit by Chinese President Xi Jinping. The first explosion occurred in a car in a nearby parking lot, followed by a second outside the court; the man's identity remains unknown due to suspicious objects found near his body. Preliminary investigations suggest a possible 'lone wolf' attack, though motives are unclear. Authorities have restricted access to the area and are conducting thorough investigations to ensure no further threats. President Luiz Inácio Lula da Silva was not present at the time of the explosions, which took place in the Plaza of the Three Powers, a central location housing Brazil's key government buildings.
