As Mali tries to restore order after the recent coup, a key challenge for the interim civilian government will be getting aid to people as the country verges on a humanitarian disaster.

Dioncounda Traore took over as Mali’s interim president on Thursday after leaders of a March 22 coup agreed to return power to civilians. Nearly 80 percent of Malian territory comprising the northern regions of Gao, Timbuktu and Kidal is under the control of a mix of Tuareg-led rebels, who have declared an independent state in the north, and armed Islamic groups.

Aid agencies say about 100,000 internally displaced people urgently need assistance including shelter. Residents of some northern towns say they are trapped without food, water, electricity, money and medical care.

The World Food Programme and the International Committee of the Red Cross,reduced their operations in the north after being ransacked by armed groups at the end of last month. Other aid agencies including Oxfam were also ransacked.

As the humanitarian situation worsens, some Malians are calling for more aid to reach their compatriots. On Tuesday 2,000 people who marched through Mali’s capital Bamako, appealing for foreign help to dislodge Tuareg-led rebels in the north, saying a humanitarian crisis was looming and civilians had been abused.
