As French troops ramp up their aerial bombardment of northern Mali, which began on January 11 in an effort alongside the Malian army to push back Islamist militants seizing the region and threatening the capital Bamako, other countries have begun offering their support. On Monday, the United States announced they would contribute intelligence and support, while Britian is lending logisitical support, and a handful of African nations are deploying thousands of troops in the coming days.
