Two gunmen stormed into the headquarters of controversial satire magazine Charlie Hebdo in Paris, minutes after the magazine tweeted a cartoon of ISIS leader Abu Bakr al-Baghdadi on Wednesday.
The magazine posted a cartoon on its Twitter account showing Baghdadi, with a message in French that mockingly wished the terrorist a 'Happy New Year'' and a 'particularly good health', according to The Guardian.
The cartoon probably referred to reports of Baghdadi being injured in coalition strikes.
Other reports suggested that the cartoon had the following message - "Still No Attacks in France. Just wait — we have until the end of January to present our New Year's wishes.''
This message could be aimed at the alleged threats by the Islamic State to launch a terror attack in France.
The gunmen reportedly shouted 'Allahu Akbar' before opening fire, a chant that has come to be eerily common in several terror attacks across the world. The militants killed several cartoonists of the magazine, including the editor Stéphane Charbonnier as per reports.
However, connections of the attack are being made with the magazine's controversial cartoon of Prophet Muhammad in 2011, following which the office was attacked by Islamists. The magazine published similar caricatures in 2012 as well.
The editor had received death threats following the cartoon of the Prophet.
In Wednesday's shooting, the gunmen also reportedly shouted "We've avenged the honor of the prophet!" after gunning down 12 people.
