The European Union is doubling its funding for an African body aimed at combatting armed groups across the Sahel region.

Leaders of five African countries are in Brussels for a security fundraising summit.

They need to raise more money to fund a joint military force that works alongside French and UN troops.

More than 50 countries are at the donor conference, including the US.

The so-called G5 Sahel group is made up of soldiers from Mauritania, Mali, Burkina Faso, Niger and Chad.
