STEVE INSKEEP, HOST:
Now, across Mali's border, in the interior of Algeria, rebel groups seized attention last week when they took hostages at an oil and facility. They claimed that they were fighting in support of Mali's Islamist rebels. And regardless of their motives, the attack raises a wider concern.
North Africa is an important source of energy resources. If oil and gas installations are no longer secure there, the price and supply of energy could be affected worldwide. That is the subject of today's business bottom line. NPR's Tom Gjelten has been speaking to risk analysts about the Algeria attack.
TOM GJELTEN, BYLINE: The early signs suggest that Algeria attack has not had a huge impact in the energy world. The price of oil, a good indicator of anxiety in the energy market, went up modestly right after the attack, but then it stabilized. No energy company has suspended operations in North Africa, nor has any company announced it will hold off on future investments. But it may just be that governments and energy companies are still trying to figure out exactly what happened at the gas field. David Goldwyn, a former State Department envoy for international energy affairs, notes that the complex had not been attacked during decades of civil war in Algeria and was surrounded - in his words - by a ring of steel.
DAVID GOLDWYN: You had a tremendous amount of desert. You had a perimeter, which was far from the actual operations, and you had interior additional perimeters as you got closer to the operating facilities. So frankly, it remains a mystery to me still how it was that this group of terrorists were able to penetrate this.
GJELTEN: It's possible the Algerian government, which is responsible for the security at its oil and gas installations, simply grew complacent. Not knowing how it happened, it's hard to know whether it could happen again. Goldwyn, now a private energy consultant, says if it was an inside job or some individual letting down his guard, the attack is less likely to be repeated elsewhere.
GOLDWYN: If the answer is a third alternative, which is that the force capability of these terrorists is greater than the security precautions in place can prevent, then that's going to dictate a hardening of the security perimeter and an increase in the lethality of the folks on the inside in order to deter those sorts of attacks.
GJELTEN: Higher fences, more guards and more guns. That, surprisingly, is the most catastrophic terrorist attack ever on a gas or oil facility in North Africa; the seizure of the Algerian gas complex has grabbed the attention of energy companies in the region.
GEOFF PORTE, RISK ANALYST: It's clearly a wake-up call.
GJELTEN: Geoff Porter is a risk analyst specializing in North Africa.
ANALYST: I think what oil companies are now trying to determine is whether this was an isolated incident or whether this is the beginning of a new security paradigm in North Africa and we're likely to see repeat attacks in the months and years to come.
GJELTEN: Militant Islamists are on the rise across North Africa and may now be targeting energy facilities. Though the Algeria attack was the most dramatic, it was not the first. Terrorists took hostages at uranium mines in northern Niger in 2010. If security becomes an even bigger problem for energy companies in North Africa, they'll have to consider the higher costs they would face; so would the governments who bear most of the security responsibilities. But it may be worth it. Scott Stewart, a counterterrorism analyst at Stratfor, a private intelligence firm, points out that after the government in Niger tightened security at its uranium mines, they were not hit again.
SCOTT STEWART: I think we'll see a similar thing happening in Algeria and probably other countries in the region, because these - the incomes they receive from these extractive industries are so critical to the national economies. They really need to protect them, and they will put a lot of resources toward safeguarding them.
GJELTEN: In the case of Algeria, it's clear the government is eager for foreign energy companies to continue investing in the country. Just this week, the Algerian parliament approved a new law lowering taxes on foreign firms in the country, something foreign investors there have long been pushing for.
