This week’s edition of French satirical magazine Charlie Hebdo will show a cartoon depicting the Prophet Muhammad holding a “Je suis Charlie” sign, the BBC reports.
Above the cartoon are the words “All is forgiven”. This comes after Islamist gunmen last week raided the magazine’s Paris office, killing 12 people.
Meanwhile, French MPs will gather for the first time since the attack.
In Israel, the funerals will be held of four Jewish victims of a separate Paris shooting by an Islamist gunman.
A total of 17 people were killed in three days of terror attacks in the French capital last week.
About 10,000 troops are being deployed across France after the attacks, and a huge unity rally was held in Paris on Sunday.
The latest cover of Charlie Hebdo has been published in advance by French media.
The slogan in French “Je suis Charlie” (“I am Charlie”) was widely used following the 7 January attack on the magazine, as people sought to show their support.
Three million copies of Wednesday’s edition are being printed. Normally only 60,000 are sold each week.
Charlie Hebdo’s lawyer Richard Malka told France Info radio: “We will not give in. The spirit of ‘I am Charlie’ means the right to blaspheme.”
Survivors of the massacre have been working on the magazine from the offices of the French daily newspaper Liberation.
Five of Charlie Hebdo’s cartoonists – including the editor – were killed in the attack.
The new edition will be created “only by people from Charlie Hebdo”, its financial director, Eric Portheault, told AFP news agency.
Contributions from other cartoonists were declined.
