Eleven troops and four civilians were killed in strikes on Sunday in Mali and Burkina Faso, two neighboring West African nations battling deadly Islamist insurgencies, according to military and security sources.

Suicide bombers drove automobiles filled with explosives into three military installations in central Mali before morning, according to the military. Six people were murdered and 15 were injured in the Sevare camp, while five people were injured at two other sites.

Across the border in northern Burkina Faso, armed gunmen assaulted a military post in Gaskinde early on Sunday, killing five troops and four civilians, according to two security sources.

In the previous two years, military juntas have seized power in Mali and Burkina Faso, offering more security than their democratically elected predecessors.
