Medecins Sans Frontieres (Doctors Without Borders, or MSF) called on Wednesday for the provision of emergency aid for over 500,000 people in northeastern Nigeria living in "catastrophic" conditions.

Over half a million people are said to be living in unsanitary conditions in several villages and town across the state of Borno.

"People have almost no access to humanitarian aid. People are gathered, isolated and cut off in a half-destroyed town, and are totally dependent on external assistance, which is cruelly lacking. If we don’t manage quickly to provide them with food, water and urgent medical supplies, malnutrition and disease will continue to wreak havoc," MSF emergency program manager Hugues Robert was quoted as saying in an MSF press release.

MSF medical teams` estimates characterize the mortality rate in the area around the Banki town as "extremely high."
