(CNN) -- Two of Pope Francis' grandnephews and the boys' mother were killed early Tuesday in an Argentina car crash that also seriously injured the pontiff's nephew, police said.
A car driven by the Pope's nephew, Emanuel Horacio Bergoglio, struck a truck on a highway in Cordoba at about 12:30 a.m., Cordoba police spokeswoman Carina Ferreyra said.
Emanuel Bergoglio's sons -- Jose Bergoglio, 8 months, and Antonio Bergoglio, 2 -- and his wife and the boys' mother, Valeria Carmona, 36, died, police said.
Emanuel Bergoglio, 35, was taken to a hospital in Cordoba, where he was in critical condition Tuesday morning, Ferreyra said.
Pope Francis, the former Jorge Mario Bergoglio, is a native of Argentina, where he was ordained as a Roman Catholic priest in 1969. He was archbishop of Buenos Aires from 1998 until he became Pope in March 2013.
