According to the AFP, the demonstrators, led by Chadian Prime Minister Kalzeube Pahimi Deubet, marched while chanting "from our territory, we will fight the forces of evil."
The country's parliament voted on Friday to send the Chad's forces to Nigeria and Cameroon, to combat Boko Haram fighters, according to Jeune Afrique. Chadian authorities are concerned about the humanitarian situation as the refugees from Boko Haram' massacres come from a region known for widespread cases of polio, cholera and Ebola, according to RFI.
Boko Haram is a Nigerian military group which was founded in 2002 and is seeking to impose Sharia law in the country. It has been blamed for over 10,000 deaths over the last five years. Its name means "Education is Forbidden" in the local Hausa language.
In late December 2014, Cameroon carried out its first-ever airstrikes against Nigeria-based militants after the terrorist group assaulted five villages and captured a military base in the country's north.
