Multinational Offensive Against Boko Haram Continues
"Through these bombings, we seek to neutralize the enemy, and pave the way to the liberation of Gamboru" through a land operation, a Chadian officer told AFP on Sunday.
On Sunday, Boko Haram struck the city of Maiduguri, capital of Nigeria's Borno state, as suicide bombings rocked cities in bordering states. The same day, the Chadian and Cameroonian joint forces struck Boko Haram targets in Gamboru and secured cross-border bridges while bringing in more troops.
On Saturday, African leaders meeting for the African Union' Peace and Security Council, announced the creation of a 7,500-strong multinational force to combat Boko Haram, AP reported. The same day, the Chadian army launched air strikes against Boko Haram positions in Gamboru.
In October 2014, the leaders of Niger, Nigeria, Chad and Cameroon announced plans to step up the fight against Boko Haram with an additional battalion and a command center to tackle the group, and Chad began its operation in mid-January. Chad is considered impacted by this conflict not only because it is harmed by Boko Haram, but also because it faces a dire humanitarian situation as refugees flee to the country as Boko Haram's influence spreads in Nigeria.
On January 4, Boko Haram militants captured the town of Baga in Borno State, reportedly killing hundreds. "The human carnage perpetrated by Boko Haram terrorists in Baga was enormous," Muhammad Abba Gava, a spokesman for a local defense group that fights militants, told the Associated Press.
