Ongoing conflict with Boko Haram, across West Africa's Lake Chad Basin region, has forced more than 2.6 million people to flee terrifying violence in Nigeria, Niger and Chad, cutting them off from their livelihoods and essential services, and destroying vital infrastructure, Oxfam said in a new statement. The notable humanitarian organization added that the number of displaced people in the most affected areas has tripled over the last two years. Often moving from one place to another over a matter of months, as they fear for their safety. Most of the displaced families are sheltered by communities that count among the world's poorest, in informal settlements that lack access to basic services like water and sanitation. Having left everything behind, their homes ruined and their lives completely disrupted, large numbers of women, men, girls and boys live in extreme vulnerability.
