On January 16 Islamic militants staged an audacious attack on a major natural gas complex in southeastern Algeria, 800 miles southeast from the capital. A jihadist group calling itself the Masked Brigade—led by Moktar Belmoktar, the fierce one-eyed veteran of the Afghan war and a senior commander of al-Qaeda in the Islamic Maghreb (AQIM)—claimed responsibility for the raid on the In Amenas gas facility near the Libyan border. Dozens of foreign hostages were taken, including at least seven Americans, as well as workers from Britain, Ireland, Norway, Japan, and other countries.

On January 17 government forces launched an operation to retake the facility. On January 18 the crisis was still continuing. Some hostages have been freed but an unknown number of others were reported killed, either by their captors or by the Algerian army fire. There has been some dismay in Western capitals over the speed and ferocity of the authorities’ response. The Algerian government strongly defended its action. “Those who think we will negotiate with terrorists are delusional,” said Mohamed Said Belaid, Algeria’s communications minister. “Those who think we will surrender to their blackmail are delusional.” The assessment seems right: allowing the attackers to escape to Libya with the hostages, or settling in for a long siege, was exactly what the Masked Brigade leaders would have hoped for.

The raid on In Amenas is the most significant military event in North Africa since the end of operations in Libya in October 2011. It was more sophisticated than the attack which killed Ambassador Christopher Stevens and three other Americans in Benghazi last September 11. Its implications are far more momentous than the escalating jihadist insurgency in the landlocked and dirt-poor Mali, bordering Algeria to the south.

Western media reports have taken scant notice of the proximity of the Libyan border to In Amenas, which is a significant omission. It now seems certain that the attackers came from a stronghold in Libya, across the unguarded desert. If this is confirmed, the attack would provide further evidence that the NATO-led war—in addition to plunging Libya into chaos—has given a boost to jihadist activity in the region. It has also enabled the militants to amass a substantial arsenal of modern weaponry: Belmokhtar’s faction is known to have commandeered vast quantities of weapons from Libyan military stockpiles at the end of the war. AQIM fighters are well poised to try destabilizing Algeria again, now that they have established a cross-border sanctuary which was denied them by Qaddafy.

AQIM was formed in 2007 by veterans of two Algerian groups that fought the government during the fierce civil war in the 1990’s, the Salafist Group for Preaching and Combat and the Armed Islamic Group. It is one of the jihadist network’s biggest, richest and most heavily armed subsidiaries. Its “Masked Brigade” is said to have carried out the attack in retaliation for Algeria’s agreement to let France use its air space to supply French forces battling Islamic militants in Mali, but the assumption is too optimistic. It would have been impossible to plan such a complex operation barely a week since the beginning of the French operation in Mali. The attack must have been planned well in advance of the French military involvement, with the air space issue providing a misleading pretext which the Western media have been all to willing to accept at face value.

The Algerian extremists have bigger fish to fry. Their wider objective is to reignite the Islamic insurgency in Algeria, which the secularist government successfully suppressed over a decade ago. The authorities officially lifted the 19-year-old state of emergency in February 2011, just before the “Arab Spring” spread to Libya.

The jihadists’ new strategy may be gleaned from the fact that the assault on In Amenas is their first major attack ever on an Algerian hydrocarbon installation. Algeria is the third-largest gas supplier to Europe and one of the world’s biggest producers of liquefied natural gas. Well aware of the importance of energy revenues the rebels refrained from attacking production facilities in the 1990’s, hoping to reap the benefits after an eventual regime change. Targeting such facilities now indicates that they are smarting for a new, long fight. They are initially aiming to destroy Algeria’s image as a safe location for foreign oil and gas companies to invest and operate. In the long run they are hoping to make Algeria the next domino.

The effects of the attack were felt immediately. Snam Rete, which operates the Italian gas network, announced on January 17 that volumes of gas pumped into Italy from Algeria through a vital trans-Mediterranean pipeline had fallen from over 70 million cubic meters a day (mcm/d) to just over 60 million—a drop of 15% at a time of peak consumption.

The implications of a renewed conflict in Algeria for European energy security are immense. If similar attacks spread to the scantily protected oil and gas fields in southwest Libya, which has no effective military force controlled by the government in Tripoli, the consequences would be potentially disastrous for the consumers in Italy, France, and points further north. Algeria is the third-largest supplier of gas into the European Union (after Russia and Norway), and In Amenas’ output alone covers two per cent of total European demand, accounting for 18 per cent of Algeria’s gas exports and earning $4 billion a year in export revenues.

Russia’s Gazprom may step in to make up the shortfall, as it did in 2011 when the war in Libya brought its gas exports to an abrupt halt, but an important consequence may be to draw Europe and the United States apart on the key issue of energy politics. An ever-greater reliance on Russia’s gas runs counter to the U.S. strategy of nudging Europeans to diversify their supplies by increasing deliveries from majority-Muslim countries. Most Europeans are lukewarm about the stalled Nabucco pipeline, which has been strongly favored by the U.S., and their misgivings are bound to be reinforced by the latest developments across the Mediterranean.

The latest crisis is the direct consequence of the ill-advised, unnecessary, and self-defeating NATO intervention in Libya. It is but another reminder that Western interventionism in the Muslim world is a form of psychosis which harms the interests of the intervening powers, brings nothing but misery to the targeted lands and peoples, and benefits only the darkest enemies of civilization in today’s world.
