An advance unit of hundreds of Chadian troops, backed up by a column of tanks, arrived at Cameroon's northern border town of Kousseri Jan. 17, greeted with cheers by local residents terrorized by Boko Haram. The intervention force, approved by Chad's parliament, is to number in the thousands. Days earlier, most of the residents of nearby Kolofata were forced to flee after an attack by Boko Haram. Cameroon troops killed 143 insurgents in a gun battle that lasted more than four hours, the army said.

Biya sent some 1,000 troops to the border to fight Boko Haram after the wife of deputy premier Amadou Ali was captured in July by suspected militants. A French-led initiative calls for Nigeria, Niger, Cameroon and Chad to contribute 700 troops each to a multinational force against Boko Haram.

Over the past five days, Boko Haram has seized five towns in Nigeria's northeast, killing hundreds and leaving thousands of residents fleeing for safety as it continues its quest to establish a "caliphate" in the country. The towns captured include Bara in Yobe state, Banki and Bamain Borno state, and Madagali and Gulakwere in Adamawa state. Boko Haram forces were driven from Bama, in Borno state, after intense aerial bombardment by Nigeria's air force Sept. 7. Tension is mounting in Maiduguri, the Borno state capital, amid fears that the insurgents are mounting an offensive on the city. Further territorial gains by Boko Haram could worsen a dire humanitarian situation. Thousands of refugees have sought sanctuary in Maiduguri, and the UN estimates that 9,000 fleeing violence have arrived in Cameroon in the past ten days, with another 2,000 crossing into Niger, which has already taken in 50,000 refugees since May 2013.

Saadi Qaddafi, son of former Libyan leader Col. Moammar Qaddafi, was extradited from Niger back to Libya on March 6 to stand trial for crimes allegedly committed during his father's rule. Saadi is the most recent fugitive whom the Libyan government has extradited from Niger. In February Abdallah Mansur, a former top intelligence official and fifteen other former Libyan officials were sent back to Libya after Niger accused them of plotting to overthrow the current Libyan government. In 2011 Interpol issued a "red notice," requiring member countries to arrest him. Niger had previously declined to extradite Saadi due to concerns that he would be executed upon return.

The authorities in Yaoundé, the Cameroonian capital, have set up tighter border controls in the Far North region to guard against infiltration by jihadist Boko Haram fighters from neighboring Nigeria as civilians flee insurgent attacks and a Nigerian military offensive, seeking safety across the border in Cameroon.

There are security control posts along the border to reduce illegal entry," said Bob-Iga Emmanuel, the head of police division at the governor's office in the Far North region.

Gilles Jaron said the new campaign, dubbed "Operation Hydra," was undertaken joinlty with Malian army forces and troops from MINUSMA, the UN force for the country. "It is the first time we have seen forces of significant size working together," Jaron said. (NYT, IBT, Al Jazeera, Oct. 24)
