Al-Qaeda in the Land of the Islamic Maghreb (AQIM), to give its full name in English, has its roots in the bitter Algerian civil war of the early 1990s, but has since evolved to take on a more international Islamist agenda.
Its reach has also expanded across the Sahel region south of the Sahara Desert, attracting members from Mauritania, Morocco, Niger and Senegal as well as from within Mali where, in alliance with other Islamists, it is fighting French troops on the ground.
During the Mali crisis, its fighters have dramatically increased their profile, allowing them to further their aim of spreading Islamic law and jihad across West Africa.
AQIM’s influence over other nascent Islamist cells comes from its wealth: it is one of the region’s best-armed groups thanks to the money it makes from kidnapping Westerners and drug and cigarette trafficking across the Sahara.
It emerged in early 2007, after a feared militant group, the Salafist Group for Preaching and Combat (GSPC), aligned itself with Osama Bin Laden’s international network.
Back in the 1990s, against a background of Islamist political groups testing their strength across North Africa, the military-backed authorities in Algeria at first permitted the Islamists to play a full part in the nation’s political life.

David Cameron has said the British people must “have their say” on Europe as he pledged an in/out referendum if the Conservatives win the election.

The news was welcomed by Eurosceptics who have long campaigned for a vote.
France and Germany both warned the UK could not “cherry pick” EU membership.
