A man has been sentenced to 30 years in prison for helping an Islamist attacker who killed five people at a French Christmas market in December 2018.

Audrey Mondjehi, 42, was convicted of obtaining a gun used by Cherif Chekatt, who shot and stabbed his victims in Strasbourg, north-eastern France.

The pair were former prison cell mates, the trial was told.

Two other men were handed shorter sentences for assisting Chekatt. A fourth man was acquitted.

Five people were killed when Chekatt opened fire on the crowd at the festive market. He was shot dead by police two days later.
