Kabila said the roughly 20 well armed gunmen were from Algeria itself, operating under orders from Moktar Belmoktar, al-Qaida’s strongman in the Sahara.
In Washington, U.S. State Department spokeswoman Victoria Nuland confirmed that “U.S. citizens were among the hostages.”
The caller to the Nouakchott Information Agency, which often carries announcements from extremist groups, said the kidnapping was carried out by “Those Who Signed in Blood,” a group created to attack the countries participating in the offensive against Islamist groups in Mali.
The Masked Brigade was formed by Belmoktar, a one-eyed Algerian who recently declared he was leaving the terror network’s Algerian branch, Al-Qaida in the Islamic Maghreb, to create his own group. He said at the time he would still maintain ties with the central organization based in Afghanistan and Pakistan.
The name of his group could be a reference to the nomadic Tuareg inhabitants of the Sahara, known for masking their faces with blue veils.
A close associate of Belmoktar blamed the West for France’s recent air and ground intervention against Islamist fighters in Mali.
“It’s the United Nations that gave the green light to this intervention and all Western countries are now going to pay a price. We are now globalizing our conflict,” Oumar Ould Hamaha told The Associated Press by telephone Wednesday night from an undisclosed location.
French President Francois Hollande launched the surprise operation in Mali, a former French colony in West Africa, on Friday, hoping to stop the al-Qaida-linked and other Islamist extremists whom he believes pose a danger to the world.
Further kidnappings could well be on the horizon, warned Sajjan Gohel, the international security director for the Asia-Pacific Foundation.
“The chances are that this may not be a one-off event, that there could be other attempts in Africa — especially north and western Africa — to directly target foreign interests,” he said. “It’s unclear as to what fate these individuals may meet, whether these terrorists are going to want a ransom or whether they’ll utilize this for propaganda purposes.”
Wednesday’s attack in Algeria began with an ambush on a bus carrying employees from the massive gas plant to the nearby airport but the attackers were driven off, according to the Algerian government, which said three vehicles of heavily armed men were involved.
“After their failed attempt, the terrorist group headed to the complex’s living quarters and took a number of workers with foreign nationalities hostage,” the government said in a statement.
Attacks on oil-rich Algeria’s hydrocarbon facilities are very rare, despite decades of fighting an Islamist insurgency, mostly in northern Algeria.
In the last several years, however, al-Qaida’s influence in the poorly patrolled desert of southern Algeria and northern Mali and Niger has grown and the group operates smuggling and kidnapping networks throughout the area. Militant groups that seized control of a vast section of northern Mali last year already hold seven French hostages as well as four Algerian diplomats.
