The United States said it condemned today's deadly shooting attack on a French newspaper in the "strongest possible terms."
"Everybody here at the White House are with the families of those who were killed or injured in this attack," White House spokesman Josh Earnest said, speaking on MSNBC.
At least 12 people were killed when gunmen armed with Kalashnikovs and a rocket-launcher opened fire in the offices of French satirical weekly Charlie Hebdo today, said sources close to the investigation.
