LONDON, England (AP) — A series of hit-and-run incidents in the Welsh city of Cardiff killed a woman yesterday and injured 11 other pedestrians, including seven children. Witnesses described a motorist deliberately driving into families walking home from school.

South Wales Police said a 32-year-old woman had been killed, and other victims were taken to hospital for treatment. An unidentified 31-year-old man has been arrested and a van has been seized.

Authorities said that there had been at least five separate hit-and-run collisions across the city.

Ramesh Patel, who runs a store close to the site where the woman was killed, said customers had described how the van driver appeared to target pedestrians. "Customers have said a white van purposely drove at people," Patel said.

The incidents took place as parents were collecting children from nearby schools and walking home.
