French police suspect sabotage in a train derailment in northwest France that injures 44 people, including one seriously. Investigators say the incident occurs a day before the reports, and at least one passenger is described as being in critical condition, including an 18-year-old woman.

According to a police source cited by multiple outlets, investigators find a fragment of rail on the track. This evidence leads them to treat the derailment as a possible malicious act rather than an accident. One report states that one person is gravely injured, while another specifies the critical condition of the 18-year-old. The outlets do not provide further details on who may be responsible or what form the alleged interference took.

Overall, the coverage aligns on the central points: the derailment occurs in northwest France, it leaves 44 people injured, and police investigations consider sabotage due to a rail fragment found on the track. Authorities continue investigating the cause and circumstances of the incident.
