Colo Colo, the Chilean football club, celebrated its 100th anniversary with nationwide festivities, including fireworks and tributes from rival teams such as Universidad de Chile and Universidad Católica, as well as football figures like Jorge Valdivia and Barticciotto. The club unveiled a model of its new Estadio Monumental, inspired by Mapuche culture and international standards, with a planned capacity of 60,000 spectators and an expected completion timeline of three to four years. A statue honoring club icon Arellano was also inaugurated at the stadium. Concurrently, the celebrations were marred by violent incidents, including clashes between Colo Colo and Universidad de Chile supporters that resulted in one death and six injuries. In La Serena, authorities confirmed the discovery of dismembered human remains identified as Ana María Pizarro, a woman who had been missing earlier in the month. Meanwhile, in the Biobío region, a terrorist arson attack targeted the Rucalhue hydroelectric plant, destroying 51 vehicles. The Chilean government, led by President Gabriel Boric and Security Minister Luis Cordero, condemned the attack and announced the invocation of the country's anti-terrorism law to prosecute those responsible. The government also plans to file legal actions related to other recent arson attacks in Quilaco and Contulmo. The incident has raised concerns among Chinese investors, given the plant's Chinese ownership, prompting calls for enhanced security measures. The attack has impacted business confidence in Chile's energy sector.
