Suspected Boko Haram jihadists attacked a village in northern Cameroon early on Tuesday, torching homes and killing two civilians just days before legislative and municipal elections, security sources said."Boko Haram made an incursion a little before 02:00 in Mozogo village," in the Extreme-Nord province "killing two people," a police officer told AFP.They torched about 20 homes and two motorbikes and stole another five motorcycles, the officer said.An army officer confirmed the incident.Security has been tightened in Cameroon ahead of Sunday's elections. Anglophone separatists are fighting government troops in western Cameroon while the north of the country has come under attack from Boko Haram.Based in neighbouring Nigeria, Boko Haram has stepped up attacks from bases hidden in the vast Lake Chad area, where the borders of Cameroon, Chad, Niger and Nigeria converge.Cameroon says the group has carried out nearly 13 000 attacks on its territory since 2014, with the loss of "several thousand" lives. The insurgency has forced more than 250 000 people to flee their homes and triggered an influx of 60 000 people from Nigeria.Boko Haram was formed in Nigeria but attacks have spread to neighbouring countries. The group has also split and a faction affiliated with the Islamic State group, ISWAP, is particularly active around Lake Chad.
