A driver has plowed into pedestrians in Modena, Italy, injuring eight people. Four are in critical condition, according to the mayor. On Saturday, a woman was pinned against a shop window and required leg amputations. The driver, a 31-year-old man, was detained and questioned. Authorities are investigating whether he was under the influence or acted deliberately. Witnesses reported he held a knife but did not stab anyone. Emergency services responded, and the area was cordoned off. Victims were taken to hospitals in Modena and Bologna, some by helicopter.

Residents of a small central Illinois city are mourning the loss of three children and a teenager who were killed in a startling vehicle collision in a building that hosts a popular after-school camp. Authorities say it appears the crash Monday, in which a car barreled through the building in Chatham, was not a targeted attack. Illinois State Police say the 44-year-old driver is not in custody. She was not injured but was taken to a hospital for evaluation, and toxicology reports are pending. Chatham is about 12 miles from the state capital, Springfield.

Illinois State Police say a car smashed through a building during an after-school program just outside Springfield, Illinois. Police say four people between the ages of 4 and 18 were killed and several others were injured. Officers responded at about 3:20 p.m. Monday to calls about a vehicle ramming through the building, hitting four people before exiting the other side. Police say several other people were hurt and taken to hospitals. The driver was uninjured and was the sole occupant of the vehicle. It isn't known what led up to the crash or whether it was intentional.
