BAMAKO

A suicide attack in the disputed north Malian town of Tabankort has killed at least five people.

A source for the main Tuareg rebel group MNLA said multiple suicide bombers from a rival, pro-government militia attacked their positions, killing 13 people.

A second source said five separatist fighters had been killed.

Fighting between rival armed groups vying to control Tabankort has broken out several times this month, prompting the UN peacekeeping mission MINUSMA to carry out air strikes on Tuareg rebel forces.

The incident, which separatists called a violation of a ceasefire deal, threatens to derail upcoming peace talks in Algiers over the future of northern Mali.

The weak Bamako government is struggling to restore its authority on northern zones where a medley of armed groups operate as well as al-Qaeda-linked Islamists who briefly occupied the region in 2012.

In a sign of high tensions, witnesses said UN peacekeepers had fired lived rounds at demonstrators protesting against a new disarmament plan on Tuesday, killing three. MINUSMA said they were only warning shots and it would launch an inquiry.
