The Paris prosecutor’s office has said it has opened an investigation into the comedian Dieudonné M’bala M’bala, after a Facebook post in which he said “I feel like Charlie Coulibaly”.

The post from Dieudonné, who has faced allegations of anti-Semitism for a gesture that many say mimics a Nazi salute, has since been taken down.

It merges the names of Charlie Hebdo, the satirical newspaper where two gunmen massacred 12 people, with that of Amedy Coulibaly, who prosecutors say killed four hostages at a kosher supermarket.

All three gunmen were killed in nearly simultaneous raids by security forces on Friday.

The investigation for “defending terrorism” was opened on Monday, said Agnes Thibault-Lecuivre, a spokeswoman for the prosecutor.
