At least 15 people died when a bus carrying about 60 pilgrims overturned in northeastern Brazil. The accident happened Tuesday morning on a curved highway stretch in rural Alagoas state. Three children were among the dead. Some survivors were airlifted to the hospital for treatment. Footage on social media showed the bus turned on its side with debris around it. Emergency crews responded quickly. Authorities said the driver seemed to have lost control before the bus left the road and rolled over multiple times. The most serious injury was a nine-year-old child with a head wound. The travelers were returning from the pilgrimage of Our Lady of Candeias, a religious festival in Ceará state. The bus was part of a convoy moving hundreds from Coité do Noia in Alagoas to Juazeiro do Norte in Ceará, a 563 km journey that takes about eight hours. The crash occurred in São José da Tapera near the end of the return trip. Bueno Higino Filho, mayor of Coité do Noia, said, "The loss is immense. They were all my friends... I woke up today to the sad news and I'm heading to the site of the accident to see what we can do [to help]." The governor of Alagoas declared three days of mourning. Paulo Dantas wrote on social media, "I stand in solidarity with the family members and friends in this moment of such great pain."
