French President Francois Hollande declared war on ISIS in France and in the terrorist group's stronghold in Syria.
The president spoke at a news conference on Friday in the aftermath of the deadly terrorist attacks that killed 129 people in Paris, France.
By daybreak Monday, French police conducted dozens of raids on homes in the muslim sections of Paris. Hundreds of suspected terrorists were taken into custody or placed on house arrest.
The French defense ministry confirmed that France and its allies launched airstrikes on ISIS sites in Raqqa, Syria.
One of the targets included ISIS's main headquarters located near where ISIS executioner Mohammed "Jihadi John" Emwazi was killed by a drone strike as he sat in a vehicle on Thursday.
ISIS deliberately set up its headquarters in densely populated areas of the city. But drones can hit targets with pinpoint accuracy with very few civilian casualties.
Meanwhile, American President Obama is going ahead with his plans to bring 10,000 Syrians to New Orleans next year. Obama's spokesman claims the 10,000 Syrians will be "vetted" to weed out the ISIS members who are hiding among them.
At least one of the Paris attackers traveled to Europe by hiding among Syrian refugees.
