At least 20 dead in north Mali clashes: witnesses
Gao resident Habsatou Cisse said by telephone she could see five bodies from the house in which she was sheltering, while other residents reported 11 and four bodies in two separate locations around the town.
The battle follows weeks of growing tension between the separatist Tuareg-led group MNLA and well-armed local Islamists who helped it seize the northern two-thirds of Mali in April.
