The country has seen similar violence, attacks and high-profile kidnappings before. There is an ongoing conflict in the country's north,complicated by spillover fromLibya's conflict, as well as the presence of al-Qaeda-linked groups.Itwas also the location of the high-profile 2009 kidnapping ofCanadian diplomat Robert Fowler.

Here's howMalibecame one of the world's biggertrouble spots.

Expats targeted

Friday's attacks targeted a hotel known to hostforeigners.

"This is the most expensivehotel in Bamako," says Cdric Jourde, aUniversity of Ottawa professorwho specializes in Islamic politics in Africa. "It'sthe place where expats gonot a place where the averageMalian or Bamako citizen hangs out."

In August,a hotel in the Malian city ofSevare was attacked, leavingninedead. United Nationsstaff were known to frequent the hotel. The was a similarattack at a bar in Bamako in March five people were killed.

Jourde says these al-Qaeda-linked groups could be behind today's violence, but cautions that it's still too early to tell who is responsible.

Anexpert on African politics and terrorism says the history of the country needs to be considered.

"It's important to keep in mind that very often, these types of attacks in Africa have local roots and local political reasons that need to be taken into account," says Rita Abrahamsen, an African politics expert who teaches at the University of Ottawa.

Abrahamsen attended the African Union Peace and Security Council meeting two weeks ago that focused on how tocombat extremist violencein the region.

"They [the African Union] are worried about the way in which terrorist groups appear to be able to continue their attacks both in the Sahel[region of the Sahara innorthern Africa] and the way in which they are seen to be able to link up with other terrorist groups in other parts of Africa," she says.

Power struggle

A struggle for control has been ongoing in the country's northern region for several years. According to the United Nations, the Mali government lost control of the area in a 2012 coupto different rebel groups.

One of thegroups involved was the Tuareg rebels. Atraditionallynomadic people, they havebeen seeking control ofa large portion ofnorthernMali.Abrahamsen saystheyhavehad a decades-long rebellion due to their marginalization and political exclusion in the country.

There are also several armed al-Qaeda-linkedgroups. Abrahamsen says many of them havesplintered.

"And then when we had the crisis in 2012 that was influenced by a flow of Islamists from the Libyan crisis;you had a kind of perfect storm of events there," she says.

That "perfect storm"led to a 2013 UN peacekeeping intervention, bolstered by French and African Union troops.

A fragile truce was brokeredlater that year, but the country has been volatile ever since.

Jourde says the al-Qaeda splinter groups have benefited from an effective leader inMokhtar Belmokhtar, said to be the plotter behind many high-profile attacks and kidnappings throughout northern Africa.

He hasnot only been able tobring al-Qaeda's influence to northern Mali, but he has achieved what other Islamic militants have nothe has managed to successfully align himself with, and recruit, many Tuareg rebels.

Former 'donor darling'

Abrahamsen says that before the coup in 2012, Mali wasseen as a success story on the international stage.

"We used to call it a 'donor darling,'" she says.

Donorslavished aid and assistance onthe country, due to its perceived stability and democracy. But she says it fell apart "literally almost overnight" in the 2012 coup.

"The democracy that they had was very much a surface democracy built on an exclusion of the northern group. And that's I think really at the heart of understanding the developments in Mali the inability to include vast sections of the population."

Thousands of Malians have escaped the violence by fleeing to neighbouring Niger. The UN says there are nearly 50,000 refugees there, with recentspikes in October and November. Malians have also fled toAlgeria, Burkina Faso andMauritania since 2012.
