At least 67 people were killed in a suicide car bomb attack on a military barracks in the north of Mali on Wednesday, medical sources told EFE.
The source said the death toll was subject to change as there were many people injured in the attack.
According to preliminary information, the assailant detonated a car bomb in the northern city of Gao while entering barracks where hundreds of Malian soldiers and affiliated fighters had gathered.
A military force in Gao contacted by EFE said military sources did not rule out the possibility of subsequent attacks as the assailants took advantage of the pandemonium.
No group has yet claimed the attack, which was one of the most bloody registered in an unstable country where violence is constant.
The United Nations Security Council is to analyze a report on Wednesday on the current situation in the country which highly concerns the international community.
Gao, one of the most insecure areas in the country, is not under central government control, allowing several Islamist militant groups to operate and commit frequent attacks against Army and United Nations forces.
