French police have identified all three gunmen estimated to have killed 12 people in a rampage at the Charlie Hebdo magazine office in Paris, France's Metro newspaper reports Wednesday night. 

Two of the gunmen are French nationals and natives, according to the report, and are brothers. The third, a homeless man, has been identified, but police have not yet confirmed his nationality. 

Police have reportedly positively identified the gunmen but have yet to release their names; this was confirmed in a tweet by Le Monde shortly after the Metro report aired. 

The heavily armed gunmen stormed the offices of the Charlie Hebdo weekly Wednesday afternoon, shouting Islamist slogans as they fired.

The gunmen, who are still at large, were shouting Islamic phrases, including "Allahu Akhbar" (God is great - Arabic) throughout the attack, according to several eyewitnesses. 

French President Francois Hollande has declared Thursday a day of mourning national national day of mourning in France after the attack. 

Islamism on the rise in France

Over the past month, France has seen a number of "car rampages" and massacre-style attacks by jihadists on innocent French citizens - raising tensions over France's Muslim community, which at over five million Muslims is Europe's largest. 

In December, a Burundi-born man, Bertrand Nzohabonayo, attacked French police in a suburb of Tours, leaving two officers seriously injured. 

Less than 24 hours later, a mentally ill man yelled "Allahu Akbar" before ramming his vehicle into dozens of pedestrians in the eastern French city of Dijon. 13 people were injured in that incident, which has been ruled to have no link to terrorism

Shortly afterwards, a van rammed into shoppers at a Christmas market in the western city of Nantes, injuring at least ten people. The driver in that attack also allegedly shouted "Allahu Akbar" as he carried out the rampage.

All three attacks followed months of intensifying anti-Semitism in France as well, which has seen tens of anti-Semitic incidents against Jewish shops, neighborhoods, families, and synagogues over the past year.
