French embassies and schools will be closed in about 20 countries Friday as a security precaution, French Foreign Ministry said in a statement Wednesday, after the satirical French magazine Charlie Hebdo published cartoons apparently depicting the Muslim Prophet Mohammed.

Magazine director Stephane Charbonnier said his staff is "not really fueling the fire," but rather using its freedom of expression "to comment (on) the news in a satirical way."

"It happens that the news this week is Mohammed and this lousy film, so we are drawing cartoons about this subject," Charbonnier told CNN affiliate BFM-TV on Wednesday. "It's more turning in derision this grotesque film than to make fun of Mohammed."

The "lousy film" he's referring to is "Innocence of Muslims," an amateurish, 14-minute video that mocks the Prophet Mohammed as a womanizer, child molester and killer. The video drew international attention last week and spawned heated protests in more than a dozen countries.
